80 - (4 - 1)³   Subtract 1 from 4
  80 - (3)³     Cube 3 (3 x 3 x 3)

Please help me figure this one out !!!
strojnjashka [21]
These are "composite" functions.
g(x+a)  means insert (x+a) into g(x) to replace every x:
g(x+a) - g(x) = -5(x+a)^2 +4(x+a) +5x^2 - 4x
 = -5(x^2 + 2ax + a^2) +4x +4a + 5x^2 - 4x
Now just Multiply and sum up the answer.

A rectangle is 10 feet longer than it is wide. The area is 39 square feet. Find the dimensions of the rectangle​
soldi70 [24.7K]

Answer:

length = 13 ft

Width = 3 ft

Step-by-step explanation:

Width = w ft

Length = ( w +10 ) ft

Area = 39 square ft

length * width = 39

(w +10)* w = 39

w *w + 10*w = 39

w² + 10w - 39 = 0

w² + 13w - 3w - 3*13 = 0

w(w + 13) - 3(w + 13) = 0

(w + 13) (w - 3) = 0    {Ignore w + 13 , as measurement cannot be in negative}

w - 3 = 0

      w = 3

length = 3 +10 = 13 ft
