<em>ANSWER:</em>

<h2>56+32x</h2>

<em>STEP:</em>

So, multiply -8 by the parenthesis.

Negative by negative is always positive. So, -8(-7) is 56. -8(-4x) is 32x. Now since it is positive, add 56+32x. Which you can't so keep it.

Question 3
Likurg_2 [28]

Answer:

27cm

Step-by-step explanation:

first, separate the 2 shapes you will find the area too. these would be the little 3 by 3 block sticking out on top, and the other piece.

to find the area, you have to do length times width.

you can start off with the 3 by 3 block. 3 times 3 = 9cm

next, you have to find the measurements of the rectangular shape. we know the width is 6cm. and the length of the whole shape is also 6cm. but we can take off the 3cm from the other shape. we now have 3cm leftover to be the length for the rectangle.

we can now find the area for the rectangle. 6 times 3 = 18cm.

last but not least, we can add the 2 measurements up to get the area of the whole shape. 9 + 18 = 27cm.
