4a is this statement true or false? $(3 + 4)^2=3^2 + 4^2$ the correct option was a false a true b 4b what whole number needs to be added to the right - hand side to make the statement true? $(3 + 4)^2=3^2+square+4^2$
Answer
Explanation:
Step1: Calculate left - hand side
First, calculate $(3 + 4)^2$. Since $3+4 = 7$, then $(3 + 4)^2=7^2 = 49$.
Step2: Calculate right - hand side without the unknown
Calculate $3^2+4^2$. We know that $3^2 = 9$ and $4^2 = 16$, so $3^2+4^2=9 + 16=25$.
Step3: Find the number to add
Let the number to add be $x$. We want $49=25 + x$. Solving for $x$, we get $x=49 - 25=24$.
Answer:
24
