A = LW
A = 72
L = W + 1
72 = W(W + 1)
72 = W^2 + W
W^2 + W - 72 = 0
(W + 9)(W - 8) = 0
W + 9 = 0
W = -9......extraneous solution...does not work here
W - 8 = 0
W = 8 <==
L = W + 1
L = 8 + 1
L = 9
so the width (W) is 8 ft and the Length is 9 ft
Answer:
-6w^2-5w+50
Step-by-step explanation:
1)multiply 3W into-2W and 5
2)multiply 10 into -2W and 5
3) combine like terms then sort answer in order
Differentiate both sides wrt 
:
By the chain rule, we get
Solve for 
:
-6×-6=36
f-34=36
34+36=70
f=70
the answer is D-n is greater then or equal to nine.
because the red dot starts on nine and goes up its greater than nine and because its on nine its also going to equal it. I had a problem getting the signs messed up when I learned it but I remember the sign always eats the greater number. I hope this answer could help and I'm sorry if the answer is incorrect.
