Well, one quarter of 20 is 5 (because 20 ÷ 4 = 5).  so, to find 3 quarters, we multiply 5 times 3.

5 × 3 = 15, so 3 quarters of 20 is 15.

Hello!

For this you can plug in the x values in the choices and see if you get the y value

y = -4^{3}  - (-4)

-4^3 is -64

when you subtract a negative you are just adding

-64 + 4 = 60

Then you do the second one

y =  -3^{3}  - (-3)

-3^3 is -27

-27 + 3 is -24

Then the third one

y =  -2^{3}  - (-2)

-2^3 is -8

-8 + 2 is -6

Then the last one

y =  -1^{3}  - (-1)

-1^3 is -1

-1 + 1 = 0

Since we did not get -2 the answer is D

Hope this Helps!
