perimeter = 8x - 16
A square has 4 sides of equal length, multiply length of side by 4
perimeter = 4(2x - 4) = 8x - 16

explanation:
7/10 - 1/4
14/20 - 5/20
14-5/20
9/20
Answer:
interest =360
Step-by-step explanation:
Using the formula i = prt (interest =principal x rate x time)
From the information provided p=800, t=15, r=3% (0.03)
i= 800x0.03x15
i=360
When you know your equation f(x) and they want you to find f(-4), it means that they want to know what f(x) is worth when x=-4
Therefore, you only need to plug in you x in the equation
f(x)=5x-2
f(-4)=5(-4)-2
=-20-2
=-22 (B)
