The Surface Area of composite solid:

Substitute:

<h3>Answer: The Surface Area of the composite solid is 165 ft².</h3>

Step-by-step explanation:
1) Subtract 2 from both sides.

2) Simplify 6 - 2 to 4.

3) Divide both sides by 2.

4) Simplify 4/2 to 2.

Therefor, the answer is, d >2.
Answer:
265.50000
Step-by-step explanation:
The answer is 3/10
Explaintion
Line parallel to y=x+11 so slopes are equal then
y= x+b
Passing through the point C (-6;2) then C belongs to this line
yc=xc+b
b= 6+2
b= 8
So y intercept is equal to 8
