## What is a Expression that represents the product of and 8, divided by 4

**Answer:8x/4 or 2, depends if you want it simplified**

**Step-by-step explanation:**

## Evaluate the expression 3X plus Z plus 2Y -12 if X equals 3Y equals eight and Z equals five

Hey there!

3x + z + 2y - 12

We know this information:

x = 3

y = 8

z = 5

With this information, we’ll just “fill in the blanks” (aka the parts with the exponents)

So, the expression would look like this:

(3 * 3) + 5 + (2 * 8) - 12

Now, we solve (see photo)

Therefore, the answer is 18

Hope this helps you!

God bless ❤️
