Question

which expression is equivalent to the expression below?
9(7g) + 5g
answer attempt 1 out of 3
○ 68g
○ 108g
○ 63g + 7g²
○ 12g + 9

Explanation:

Step1: Simplify \( 9(7g) \)

Multiply 9 and 7 to get \( 9\times7g = 63g \).

Step2: Combine like terms

Now we have \( 63g + 5g \). Since both terms have the variable \( g \), we add their coefficients: \( 63 + 5 = 68 \), so \( 63g + 5g = 68g \).

Answer:

\( 68g \) (corresponding to the option "68g")
