Answer:
x=4
Step-by-step explanation:
-5x+5-x+1=-18
combine like terms
-6x+6=-18
subtract 6 from both sides
-6x=-24
divide both sides by -6
x=4
Assuming that the rug is rectangular in shape, therefore
the formula of area is:
A = l w ---> 1
where l is the length of the rug and w is the width of
the rug
We are given that the width of the rug is 5 feet less
than the length, therefore:
w = l – 5 ---> 2
Combining equations 1 and 2 and knowing that A = 150 will
give us:
l (l – 5) = 150
In the given choices, l = x, therefore:
x (x – 5) = 150
Hence the correct answer is the 1st one (A)
(3x^4)^2 = (3^2)*(x^4)^2 = 9*(x^(4*2)) = 9*x^8 . . . . . the 3rd selection
