which statement could be represented by the expression: $x^2 + 8$

• the sum of twice a number and eight
• the square of the sum of a number and eight
• the sum of the square root of a number and eight
• the sum of a number squared and eight

Explanation:

Step1: Analyze each option

• Option 1: "the sum of twice a number and eight" would be \(2x + 8\), not \(x^2+8\).
• Option 2: "the square of the sum of a number and eight" would be \((x + 8)^2\), not \(x^2+8\).
• Option 3: "the sum of the square root of a number and eight" would be \(\sqrt{x}+8\), not \(x^2+8\).
• Option 4: "the sum of a number squared and eight" is \(x^2+8\), which matches the given expression.

Answer:

the sum of a number squared and eight
