Answer:
final answer is 6
Step-by-step explanation:
Given 
To find the difference quotient use formula



Now plug it in the formula




6
B, the inverse is not a function, because to the x-value 0 the inverse relation orders two values: the 1 and the 5 as well.
Length (L): 2w + 6
width (w): w
Perimeter (P) = 2L + 2w
240 = 2(2w + 6) + 2(w)
240 = 4w + 12 + 2w
240 = 6w + 12
228 = 6w
38 = w
Length (L): 2w + 6 = 2(38) + 6 = 76 + 6 = 82
Answer: width = 38 ft, length = 82 ft
Perimeter is the sum of all the sides of the shape
do you know the length of each side of the parallelogram?
X(x - 2)(x - 4)
x(x² - 6x + 8)
x³ - 6x² + 8x
