Question

variables and expressions
evaluate each expression to find the missing valu
1.
n | 7 | 9 | 22 | 35
n + 8² | 71 | | |
3.
n
n • 7

Explanation:

Step1: Recall the expression

The expression is \( n + 8^2 \). First, calculate \( 8^2 \).
\( 8^2=64 \)

Step2: Solve for n when the expression is 71

We know that \( n + 64 = 71 \). To find \( n \), subtract 64 from both sides.
\( n=71 - 64 \)
\( n = 7 \) (which matches the given value, so we can check the other rows)

Step3: For \( n = 9 \)

Substitute \( n = 9 \) into \( n + 8^2 \).
\( 9+64 = 73 \)

Step4: For \( n = 22 \)

Substitute \( n = 22 \) into \( n + 8^2 \).
\( 22 + 64=86 \)

Step5: For \( n = 35 \)

Substitute \( n = 35 \) into \( n + 8^2 \).
\( 35+64 = 99 \)

Answer:

For \( n = 7 \): \( 7+8^2=7 + 64=71 \) (matches)
For \( n = 9 \): \( 9+8^2=73 \)
For \( n = 22 \): \( 22+8^2=86 \)
For \( n = 35 \): \( 35+8^2=99 \)

(If we assume the task was to fill the table for \( n + 8^2 \) with given \( n \) values, the completed table values for the expression column would be 71, 73, 86, 99 corresponding to \( n = 7,9,22,35 \) respectively.)
