Oc) 0
O d) 5

Answer 1

a) 4

Explanation:

To find the zero of 5x - 20 = 0, find the value of x.

5x - 20 = 0

Add 20 to both sides.

5x - 20 + 20 = 0 + 20

5x = 20

Divide both sides by 5.

(5x)/5 = 20/5

x = 4

The zero of 5x - 20 = 0 is 4.

Answer 2

x=4

Explanation:

5x - 20 = 0

Add 20 to each side

5x = 20

Divide by 5

5x/5 = 20/5

x =4

The zero is when x = 4
