Answer:
lets say that the length is L and the width is W. With the given info, we can say that L=5W.
We know that the perimeter is all four sides added, so..
5W*4=20W
20W=96
W=4.8
L= 5*4.8=24
Area is equal to 24*4.8, which is 115.2
Voila! Your answer is 115.2 sq. ft!
Step-by-step explanation:
l = 2w + 4
l * w = 48
We can substitute l with its value:
2w + 4 * w = 48
2w^2 + 4w - 48 = 0
2(w^2 + 2w - 24) = 0
2(w+6)(w-4) = 0
w = {4, -6}
The value of x is 27
because 2 times 27 equals 54 minus 7 equals 47
-12
f(-3)= -(-3)2 + 6(-3)
= -(-6) -18
= 6 - 18
= - 12
