Answer:

$12x-6$

Step-by-step explanation:

For our first step, let's rearrange our equation to get our variable terms (8x and 4x) and our constants (the two 3's) together:

$8x+4x-3-3$

Taking away 3 twice is the same as taking away 6, and if we have 8 x's and add another 4 x's, that's the same as 8 + 4 = 12 x's, which we can write as 12x. So our simplified expression becomes

$12x-6$

Can you help me with this it’s so confusing plz help me with both is this

Answer:

First picture: -4,913

Second picture: 20.25

Step-by-step explanation:

-17^5/-17^2 = -17^3

-17 × -17 × -17 = -4913

4.5^5/4.5^3 = 4.5^2

4.5 × 4.5 = 20.25

Do you see how I had the same whole number on the top and bottom? (17 was on top and 17 was on bottom)

The exponents were those tiny numbers you saw.

Whenever you are dividing by the same whole number (-17/-17), you can subtract exponents.

When you multiply the same whole number, you can add the exponents.

Hope this helps! Best of luck :)
