The correct answer for the question that is being presented above is this one: "<span>D. 300 yd2."
</span>
We have to get the areas of 5 polygons and add them together to get the surface area.

Area 1 = l * w = 5*8 = 40
Area 2 = l * w = 12 * 8 = 96
Area 3 = l * w = 13 * 8 = 104
Area 4 = bh/2 = 5*12/2 =30
Area 5 = bh/2 = 5*12/2 = 30

Area = Area 1 + Area 2 + Area 3 + Area 4 + Area 5
Area = 40 + 96 + 104 + 30 + 30
Area = 300 yard^2

What is the answer to Factor 3a^2-6a

Anton [14]

Hi there!

$3 {a}^{2} - 6a \: = 3a(a - 2)$

We can see this by writing the factors as multipliers. We get the following:
$3a {}^{2} = 3 \times \: a \times a$
$6a = 3 \times 2 \times a$

Now we can see that the terms that are in common are 3 and a, and therefore we can bring those outside the parenthesis.
