Ok so basically, you are going to use the distributive property to solve this problem.
First, Use the distributive property.
So basically 3(x + 4) = 9 would be:
3x + 12 = 9 after the distributive property
Then you subtract 12 from both sides
3x = -3
Then you divide 3 by both sides
you will get x = -1
Hope this helps

Answer:
28 units²
Step-by-step explanation:
Assume that your net has the dimensions shown below.
Its area is
2 yellow rectangles = 2(4 × 2) = 2 × 8 = 16 units²
2 grey rectangles = 2(4 × 1) = 2 × 4 = 8 units²
2 green rectangles = 2(2 × 1) = 2 × 2 = <u> 4 units²</u>
TOTAL = 28 units²
The prism's surface area is 28 units².
