The answer would have to be D.
Answer:
$26.88
Step-by-step explanation:
Cost of a ply wood = $0.56 per square foot
If Dakota wants to build 8 birdhouses and he needs to paint 6 square feet of plywood for each birdhouse, then the total area fir the 8 bird house will be expressed as:
8 * 6
= 48 sq. feet
Hence the area of 8 bird houses is 46sq. feet
Next is to calculate the amount it will cost to make the 8 bird houses.
Since 1 sq. foot = $0.56
48 sq. feet = y
cross multiply
y * 1 = 48 * 0.56
y = 26.88
Hence it will cost Dakota $26.88 to make hid bird houses
You can rewrite that as:
a^2-4ab+6ab-24b^2 then factor 1st and 2nd pair of terms.
a(a-4b)+6b(a-4b) so you have
(a+6b)(a-4b)
