Answer: A. 17 - 17 = 0
Step-by-step explanation:
A variable is a number
Answer:
Plug in the x value that's given to find f(x)
So if you do it for the first one where x is -2 then f(x) should equal -23.
Do that for all of them and graph the coordinates and you should be fine
A=180-105
A=75
In the triangle
75+ 9x +12x =180
X=5

B) The cheapest deal is 24 for $56
Step-by-step explanation:
Answer:
length = 48 feet , width = 32 feet
Step-by-step explanation:
Using
2W + 2L = 160 with W = L - 16 , then
2(L - 16) + 2L = 160 ← distribute and simplify left side
2L - 32 + 2L = 160
4L - 32 = 160 ( add 32 to both sides )
4L = 192 ( divide both sides by 4 )
L = 48
Substitute L = 48 into W = L - 16
W = 48 - 16 = 32
Thus length = 48 feet and width = 32 feet
