(x+6)(x+2)
Simplifying
(x + 6)(x + 2)
Reorder the terms:
(6 + x)(x + 2)
Reorder the terms:
(6 + x)(2 + x)
Multiply (6 + x) * (2 + x)
(6(2 + x) + x(2 + x))
((2 * 6 + x * 6) + x(2 + x))
((12 + 6x) + x(2 + x))
(12 + 6x + (2 * x + x * x))
(12 + 6x + (2x + x2))
Combine like terms: 6x + 2x = 8x
(12 + 8x + x2)
Answer:
Answer Below
Step-by-step explanation:
Triangle #1
To solve this answer we need to multiply then <em>divide by 2</em>
x 
÷ 
12
Triangle #2
Now we do the same thing!
x 
÷ 
12
Rectangle #1
<em>Now we solve for the rectangle!</em>
x 
48
Now we add all these together!

<em>The answer is D. 72 Square Units</em>
as the following pic you can see the answer.
#diameter is 8 so radius is 4
