Answer:

f(-1) = 2

Step-by-step explanation:

To evaluate this function at x = -1, replace "x" in the equation with (-1) (you should use the parentheses as indicated here).

f(x)=x²-3x-2 becomes

f(-1)=(-1)² - 3(-1) -2, or

f(-1) = 1 + 3 - 2, or

f(-1) = 2

The perimeter of rectangle is twice the sum of its length and its width.the perimeter is 22 meters and its length is 2 meters mo

romanna [79]

P = 2(L + W)
P = 22
L = 2W + 2

22 = 2(2W + 2 + W)
22 = 2(3W + 2)
22 = 6W + 4
22 - 4 = 6W
18 = 6W
18/6 = W
3 = W.....this is the width

L = 2W + 2
L = 2(3) + 2
L = 6 + 2
L = 8 meters <=== this is the length
