Question

1. if x = 4 and y = 3, what is (x + y)² ?

e. 25
f. 32
g. 7
h. 49

Explanation:

Step1: Substitute x and y values

Substitute \( x = 4 \) and \( y = 3 \) into \( (x + y)^2 \), we get \( (4 + 3)^2 \).

Step2: Calculate the sum inside the parentheses

First, calculate \( 4 + 3 = 7 \), so the expression becomes \( 7^2 \).

Step3: Calculate the square

Calculate \( 7^2 = 49 \).

Answer:

H. 49
