Okay, so powers are multiplied out of parenthesis.
Every number of a variable has 1 power.
x^2 + 2^2
x^2+4

The roots of 54 are: 1 and 54, 2 and 27, 3 and 18, 6 and 9, then it restarts all over again.
The two numbers have to multiply up to 54, and add up to 3. 9 and 6 have a difference of 3, and the multiplied sum is negative, so this is your pair.
9 and -6 fit this criteria, since they add up to 3 and multiply to 64.
Answer:
blocks
Step-by-step explanation:
If it takes 15 minutes to walk 7 1/2 blocks, it should be 15:17
The left side is minutes and the right side is the number of blocks
15:17
1: ? Since we are figuring out how many blocks he can walk in a minute, the left side is 1 and the right side is a question mark because we have not figured it out yet.
15: 17 Divide by 15 on both sides because that is the "distance" from 15 to1
1 : ?

So the answer is
X= -2 + the root of 5
OR
x= -2 - the root of 5
First, let's see what the answer is when we follow this equation using PEMDAS.
5 + 4 x 2 + 6 - 2 x 2 - 1
5 + 8 + 6 - 4 - 1
14
Now, let's trying grouping 5 + 4 together, and solving it again.
(5 + 4) x 2 + 6 - 2 x 2 - 1
9 x 2 + 6 - 2 x 2 - 1
18 + 6 - 4 - 1
24 - 5
19
So, the parentheses go around 5 + 4 to get your answer!
