Step-by-step explanation:
<u>Step 1: Set up Equation</u>
"Nine more" is + 9
"Seven times a number" is 7n
"One more" is + 1
"Square of the [same] number" is n²
7n + 9 = n² + 1
<u>Step 2: Solve for </u><em><u>n</u></em>
- Subtract 7n on both sides: 9 = n² - 7n + 1
- Subtract 9 on both sides: 0 = n² - 7n - 8
- Factor quadratic: 0 = (n - 8)(n + 1)
- Solve roots: n = -1, 8

Answer:
48*F
Step-by-step explanation:
You know that the daytime high temp was 13 higher than the given low of 35.
Thus your equation would be as follows:
35 + 13 = x
35 + 13 = 48
x = 48
hope this helps you out.
good luck and god bless!
