There are 8 numbers so 536/8 which is 67.
Hope this helps :D
The answer would be y=(x+4)^2-37
Answer:
Step-by-step explanation:
36 d²-36 d+9=9(4d²+4d+1)
=9[4d²+2d+2d+1]
=9[2d(2d+1)+1(2d+1)]
=9(2d+1)(2d+1)
=9(2d+1)²
=[3(2d+1)]²
=(6d+6)²
length=6d+6
perimeter=4(6d+6)=24d+24
when d=2
length=6×2+6=18in
perimeter=4×18=72 in
area=18²=324 in²
The third story, to get area you have to multiply length times width
Answer:
21
Step-by-step explanation:
