40,023,032 = 40,000,000 + 20,000 + 3,000 + 30 + 2
Answer:
c
Step-by-step explanation:
(3x)ex2
2x-2+x+5=90
3x+3=90
-3 -3
3x/3 =87/3
x=29
144=(x+7)^2 take the square root of both sides...
12=x+7 subtract 7 from both sides...
x=5
So the original was a 5m square.

255=WL and you are told that W=L+2 so the equation becomes:
255=(L+2)L
255=L^2+2L
L^2+2L-255=0
L^2+17L-15L-255=0
L(L+17)-15(L+17)=0
(L-15)(L+17)=0 Since L>0...
L=15yd, and since W=L+2, W=17yd so
length=15, width=17yd
