Considering area (A) of garden as 30 square feet:
30 = x(2x+7)
Now we need to expand it:
x(2x+7) = 2x^2 + 7x
2x^2 + 7x = 30
Adding this into an Algebra calculator gives us 5/2 or 2.5
So x = 2.5
To prove this:
2(2.5) + 7 = 12
14 * 2.5 = 30
(2x+7) x = 30
you can distribute to make this easier
2x^2 + 7x = 30
you can plug this into quadratic formula by setting the equation =0, so:
2x^2 +7x -30 = 0
where 2x^2 = a
7x = b
and -30 = c
you can plug this into your calculator and get an answer of
X = 2.5

Aisha wants to paint the four walls of her living room. Each wall is 2.1 m high and 4.5 m long. One wall has a door of 1.8 m by 0.9 m. Tins of paint cost £10 per 1.5 L tin. Each litre of paint can cover 12 m2 of wall. There is an offer of: Buy 2 tins get the 3rd at half price. How much will Aisha pay to paint her living room?
Answers
Answer:
£25 or £20.10
Step-by-step explanation:
calculate the area to be painted:
2.1x4.5= 9.45m^2 for each wall
x4= 37.8m^2
area of door= 1.8x0.9= 1.62m^2
subtract the area of the door from the wall area
37.8-1.62= 36.18m^2 to be painted
divide the area by the area that 1L of paint can cover
16.18/12= 3.015 L needed
if 1.5L= £10 then, 3L= £20. she needs 2 cans + an extra 0.015 L- so another can (3 cans total) add price up.
£30- but buy 2 get 3rd 1/2 price, so take £5 off. price is £25
or
calculate price for 0.015L
1.5=£10
divide both sides by 100
0.015= £ 0.10
if 1.5L= £10 then, 3L= £20. she needs 2 cans + an extra 0.015 L
£20+£0.10= £20.10

A thrift store was selling an Atari 2600 for $80 before deciding to have a 40% off promotion. A customer comes in to buy the console and pays with a 10% off any one item coupon. The coupon states that the 10% off coupon applies after any in-store promotions. The customer expects to get 50% off overall and pay 40.00. Is the customer correct?
Answers
Answer:
The customer is incorrect. They will pay $43.20 not $40.
Step-by-step explanation:
Since a thrift store is having 40% of $80, we have to calculate that. Doing so, we have to create proportions:
(The "/" sign is fraction)
1. x/80=40/100 2. 40*80=3200 3. x*100=100x 4. 100x=3200
5. x=3200/100 6. x=$32
Since $32 is 40% of $80, we have to do $80-$32=$48
So the thrift shop is lowering the price to $48.
But we can't forget about the 10% off coupon from the customer.
Now we have to find out what is 10% of $48. $48/10= $4.8
That's not our answer though. The final step is to do $48-$4.8 which gets our answer of $43.20 .

Banana Cupcakes
makes 10 cupcakes
1 cup granulated sugar
cup vegetable oil
1 large egg
4 tablespoons sour cream
2 medium-sized ripe bananas, mashed
1 cups all-purpose flour
1 teaspoon baking soda
teaspoon salt
1 teaspoon vanilla extract
pinch of nutmeg
You will use the recipe above to answer the following questions:
This recipe serves 10, but you need to serve 30. What number will you need to multiply the amount of each ingredient by to adjust the recipe? How did you determine this number?
How much vegetable oil do you need for 30 cupcakes?
How much flour do you need for 30 cupcakes?
What is the difference in the amount of vanilla extract you would need for 30 cupcakes?
What is the difference in the amount of salt you would need for 30 cupcakes?
In the real world, even though you make adjustments to a recipe to accommodate the number of people you need to serve, you sometimes round the amount of an ingredient instead of using an exact amount. Which ingredient would it make more sense to round rather than coming up with the exact amount? Why?
Answers
Answer: Hey give me 1 hour and ill answer it I'm doing odessyware rn so Ill get back to you later appreciate yo patients.
Step-by-step explanation:
Then, if we want to make 30 servings, we need to use that recipe 3 times. (because x*10 = 30, then x = 30/10 = 3)
This would be equivalent to multiply each ingredient by 3.
for 30 cupcakes we need:
3 cups of vegetable oil.
3 cups of all-purpose flour
(because for each one of these ingredients we needed only 1 cup to make 10 cupcakes).
for 10 cupcakes we need 1 teaspoon of vanilla.
for 30 cupcakes we need 3 teaspoons of vanilla, the difference is 3 - 1 = 2.
So the difference is 2 teaspoons.
About which quantities we should round are those where we may have mixed numbers or big numbers.
For example, we have 4 tablespoons of sour cream for 10 servings, then for 30 servings we should have:
3*4 = 12 tablespoons.
We could round this down to 10 tablespoons.

List the sample space for rolling a fair six-sided die. S = {1} S = {6} S = {1, 2, 3, 4, 5, 6} S = {1, 2, 3, 4, 5, 6, 7, 8}
Answers
Answer:
The sample space for rolling a fair six-sided die is: S = {1, 2, 3, 4, 5, 6}
The sample space represents all the possible outcomes of an event. In this case, the event is rolling a fair six-sided die, so the sample space is the set of all the possible numbers that can appear on the die, which are 1, 2, 3, 4, 5 and 6.
Option A, S = {1}, is incorrect because this only represents one outcome, not all possible outcomes.
Option B, S = {6}, is incorrect because this only represents one outcome, not all possible outcomes.
Option C, S = {1, 2, 3, 4, 5, 6}, is correct as it represents all possible outcomes.
Option D, S = {1, 2, 3, 4, 5, 6, 7, 8}, is incorrect because this includes numbers that cannot appear on a six-sided die, and it does not represent all possible outcomes.

27x + 15y = ? (9x + ? y)
Please help! I don't understand!
Answers
Answer:
3;5
Step-by-step explanation:
One side of the equation is 27x + 15y, the number of the first blank times 9x needs to be 27x, so it has to be 3. And 3 times {blank} y needs to be 15y, so the second blank has to be 5.
Hope this helps! :)
Answer:
27x + 15y = 3(9x + 5y)
Step-by-step explanation:
27x + 15y = ?(9x + ?y)
3 times 9 = 27
so the first ? would be 3
27x + 15y = 3(9x + ?y)
15/3 = 5
so the 2nd ? would be 5
27x + 15y = 3(9x + 5y)
Simplify to check your work.
27x + 15y = 3(9x + 5y)
27x + 15y = 3(9x) + 3(5y)
27x + 15y = 27x + 15y

What is function?A function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The whole set of values that the function's output can produce is referred to as the range. The set of values that might be a function's outputs is known as the co-domain.
Given function:
f (x) = 3x – 1.
Also,
x f(x)
-5 a
-2 7
4 b
8 c
Now, using the proportionality
k = y/x
k = 7 / (-2)
k = -3.5
So, -3.5 = a/ (-5)
-3.5 x (-5) = a
a= 17.5
again, -3.5 = b/4
b= -14
Lastly, -3.5 = c/8
c= -28.
Hence, the value of a= 17.5, b=-14 and c=-28.
