Which expression is equivalent to (3×⁶ + 2׳) - ( ×⁵- 5׳)?

3x^6-x^5+7x^3

Step-by-step explanation:

So we have 3x^6+2x^3, then -x^5+5x^3 (after distributing the negative)

3x^6 cant be added to another number, neither can -x^5 so we can list them as follows

3x^6-x^5

Now 2x^3 and 5x^3 have the same exponent, so you can add them together to get 7x^3

The final solution will be 3x^6-x^5+7x^3 with exponents from highest to lowest.

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24
