Answer: D
(2x)^2 + 2(3•2x) + 3^2
4x^2 + 2(6x) + 9
4x^2 + 12x + 9
The area of any quad = the base* height
for q 1:
the base=12 in
the height= 3 in
then the area = 12*3 = 36 sq in
for q 2:
the base= 14 in
the height = 4.5 in
then the area =4.5*14 =63
Step 1: get rid of the 1/3 by multiplying both sides by 3
3 • y = 3 • 1/3(x+w)
3y = x + w
Step 2: get the x by itself by subtracting away the w
3y - w = x + w - w
3y - w = x
You’ve got your answer.
Answer is B, 21.6
Let me know if you need an explanation
You subtract 15.50 from 47.50
then you will get your answer it is 31
