how many does Carlos have?

Answer:

To simplify the expression (x+5)(3x-1)(3x-2), we can use the distributive property of multiplication and combine like terms:

(x+5)(3x-1)(3x-2)

= (x(3x-1)+5(3x-1))(3x-2) [distributive property of multiplication]

= (3x^2-x+15x-5)(3x-2) [distributive property of multiplication again]

= (3x^2+14x-5)(3x-2) [combine like terms]

To multiply the two factors, we can use the FOIL method:

(3x^2+14x-5)(3x-2)

= 3x^2(3x) + 14x(3x) - 5(3x) - 2(3x^2) - 2(14x) + 2(5) [FOIL method]

= 9x^3 + 42x^2 - 15x - 6x^2 - 28x + 10 [combine like terms]

= 9x^3 + 36x^2 - 43x + 10 [combine like terms]

Therefore, (x+5)(3x-1)(3x-2) simplifies to 9x^3 + 36x^2 - 43x + 10.

Answer:

9x^3+36x^2-43x+10

Step-by-step explanation:

(x+5)(3x-1)(3x-2)

First solve (x+5)(3x-1):

3x^2-x+15x-5

3x^2+14x-5

Then use that to multiply with (3x-2)

(3x^2+14x-5)(3x-2)

9x^3-6x^2+42x^2-28x-15x+10

9x^3+36x^2-43x+10

Answer:

9x^3+36x^2-43x+10

3/10

Step-by-step explanation:

60% is the same as 60/100

90% is the same as 90/100

90-60=30

30/100

30/100 is divided by 10 on each side to simplify it to 3/10

\((4+4+5.7)*3=41.1 \: mm\)

Answer:

answer is 57.1

Step-by-step explanation:

2(3 x 4) = 24 /// (3 x 5.7) = 17.1 /// 2.85^2 + b^2 = 4^2 ----> 8.1225 + b^2 = 16 ----> b^2 = 7.8775 ----> sqr b^2 = sqr 7.8775^2 ----> 2.806688 = hight of triangle /// 2 x 1/2(5.7 x 2.806688) = roughly 16 /// So 24 + 17.1 + 16 = 57.1

Answer: 15

Step-by-step explanation:

Write 12% as a fraction: 12/100

Since, finding the fraction of a number is same as multiplying the fraction with the number, we have: 12/100 of 125.

12/100 × 125

If you are using a calculator, enter 12÷100×125 which will give you 15 as the answer.

Answer:

B

Step-by-step explanation:

B because the y-intercept is (0,-1) and another point is (5,9). Using the slope formula, 10/5=2 so the right equation is B.

Answer:

Mean = 16

Step-by-step explanation:

MEAN can be find bg the sum of all score divided by the amount of the score.

Mean = total amount / number of amount

Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39

= 128

number of amount = 2, 3, 5, 9, 17, 22, 31, 39

= 8

Then we can calculate mean as

Mean = 128/8

Mean = 16

============================================================

Explanation:

A = 0.61 is given to us

Pumpkin B travels 0.28 of a mile further than A does, so,

B = A+0.28 = 0.61+0.28 = 0.89

Pumpkin B travels 0.89 of a mile.

---------------------

Pumpkin C travels 0.06 of a mile more than B does, which means,

C = B + 0.06

C = 0.89 + 0.06

C = 0.95

Pumpkin C travels 0.95 of a mile.

---------------------

The last thing to do is to subtract the values of C and A

C - A = 0.95 - 0.61 = 0.34

Pumpkin C travels 0.34 of a mile further compared to pumpkin A.

---------------------

Side note: if you want to convert from miles to feet, then multiply by 5280.

For instance, 0.61 miles = 0.61*5280 = 3,220.8 feet.

                                = 29

Answer:

Step-by-step explanation:

Let’s mark the Triangle Points as Point A, Point B, Point C.

Point A = 1x°

Point B = 2x°

Point C = 3x°

We know that the Angle Sum of a Triangle is equal to 180°.

So, Point A + Point B +Point C = 180°

   = 1x° + 2x° + 3x° = 180°

   = (1 + 2 + 3)x° = 180°

   = 6x° = 180°

   = x° = (180/6)°

   = x° = 30°

|  —                                 —  |

|   Point A = 1 * 30° = 30°    |         ⇒

|   Point B = 2 * 30° = 60°   |         ⇒          Only Extra Information

|    Point C = 3 * 30° = 90°  |         ⇒
