Answer:
this is just for part A sorry i dont get part B
oof bad drawing of a trapezoid
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)
M5 minus M6 will get M1
So 62 - 38 = 24
24 x 3 = 72
So M3 is 72
