Question

which expression is equivalent to the expression below?
$7(8y) + 3y$
answer
$\circ\\ 77y$ $\circ\\ 59y$ $\circ\\ 56y + 8y^2$ $\circ\\ 11y + 7$

Explanation:

Step1: Simplify \(7(8y)\)

Multiply 7 and 8 first: \(7\times8 = 56\), so \(7(8y)=56y\).

Step2: Combine like terms

Now we have \(56y + 3y\). Since both terms have the variable \(y\), we add their coefficients: \(56 + 3 = 59\), so \(56y+3y = 59y\).

Answer:

\(59y\) (corresponding to the option with \(59y\))
