Answer:
x^2(x – 9) + 5(x – 9)
Step-by-step explanation:
x^3 – 9x^2 + 5x – 45
To factor by grouping, we can take out an x^2 out of the first group of 2 terms
x^2 ( x-9) + 5x -45
We can take out a -5 out of the last 2 terms
x^2 ( x-9) + 5( x-9)
Answer:
p = 2
q = 6
r = 16
x = 5 feet
Step-by-step explanation:
The perimeter of the rectangle is

In your case,
Width = 3 feet
Length = x feet
So, the perimeter is

Since the perimeter is 16 feet, we have

Hence,
p = 2
q = 6
r = 16
Solve this equation for x:

A) (0,1), (1,-2), (-1,4), (2,-5)
b) (0,4), (-1,2), (-2,0), (1,6)
c) (-2,-7), (-1, -7), (0,-7), (1, -7)
