The equations that are true for x = -2 and x = 2 are (a) x^2 - 4 = 0 and (d) 4x^2 = 16
<h3>How to determine the true equations?</h3>
We have:
x = -2 and x = 2
Rewrite as:
x + 2 = 0 and x - 2 = 0
Multiply both equations
(x + 2)(x - 2) = 0
This gives
x^2 - 4 = 0 --- option (a)
Add 4 to both sides
x^2 = 4
Multiply by 4
4x^2 = 16 --- option (d)
Hence, the equations that are true for x = -2 and x = 2 are (a) x^2 - 4 = 0 and (d) 4x^2 = 16

Answer:
y=8+1.5x+0.75z
Step-by-step explanation:
step one:
let us initialize the variables
let the cost of pizza be y
and let additional inch be x
also, let additional topping be z
step two:
we can model the cost of pizza as
y=8+1.5x+0.75z
therefore the expression for the cost of the pizza is given as
y=8+1.5x+0.75z
Are you sure that is the full question? You can't distribute any of it that's just a simple multiplication problem. But if that is the whole equation than your answer is 128
