Answer:

  • -2.5

Step-by-step explanation:

<u>Evaluate the expression:</u>

  • b²/(a + 5)

When a= −15 and b=−5

<u>Substitute values:</u>

  • b²/(a + 5) =
  • (-5)² / (-15 + 5) =
  • 25/(-10) =
  • -2.5

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

<u>In case the expression is b²/a + 5, the value is:</u>

  • b²/a + 5 =
  • (-5)²/(-15) + 5 =
  • 25/(-15) + 5 =
  • - 5/3 + 5 =
  • 10/3

Can you simplify 3(x+2) = 3x+6 in distributive property
Vanyuwa [196]

Hello XD

3(x+2) = 3x+6

Distributive property

(3)(x)+(3)(2) = 3x+6

3x+ 6 = 3x+6

Now subtract 3x from both sides

3x+6-3x = 3x+6-3x

6=6

Subtract 6 from both sides

6-6 = 6-6

0=0

In this case the answer is : All real numbers are solution

Find the area of the composite figure.
Minchanka [31]

Answer:

132 square feet

Step-by-step explanation:

The formula for the area of a triangle is 1/2 * b * h. B stands for base and h stands for height. 1/2 multiplied by the base, 10, is 5. We then multiply 5 by 12 which is 60. Let's look at the rectangle now. The area of a rectangle is length by width. The length is 12ft and the width is 6ft. 12 * 6 = 72. 72+60=132 square feet.
