D. 29

Step-by-step explanation:

First, let's make things a bit easier for ourselves and convert mixed numbers to improper fractions

Next, we check for numbers that can cancel out. In this case, we have 10.

Because negatives cancel out, we get

when we multiply.

Fractions just mean division, so we divide 87 by 3 and get

D. 29

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

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!
