Analyze Timothy's steps. Is he correct? If not, why not?
Yes, he is correct
No, he needed to add the exponents when he
simplified the powers of the same base.
No, he needed to multiply 3 and -1 instead of
creating a positive exponent in a fraction,
No, his value of (-4) should be positive because
an even exponent indicates a positive value.

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

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

can you complete your sentence? i could !

x = 12

y = 1

for the points!
