Which expression is equivalent to the expression below? 7(4x+8)-7x 7(4x+8-7x) 35 x+8 18 x+15 21 x+56

Distribute and Multiply: First, distribute the 7 into the parentheses. 7(4x+8) = 7*4x + 7*8 = 28x + 56Subtract and Combine Terms: Now, subtract 7x from the result of the distribution. 28x + 56 - 7x Combine like terms (28x and -7x). (28 - 7)x + 56 = 21x + 56Check for Accuracy: Check the original expression and the final simplified expression to ensure that no steps have been missed and that all operations have been performed correctly. Original expression: 7(4x+8)-7x Final simplified expression: 21x + 56 No steps have been missed, and all operations are correct.

Q. Which expression is equivalent to the expression below?

\newline

7(4 x+8)-7 x

\newline

7(4 x+8-7 x)

\newline

35 x+8

\newline

18 x+15

\newline

21 x+56

Distribute and Multiply: First, distribute the $7$ into the parentheses. $7(4x+8) = 7\times 4x + 7\times 8$ $= 28x + 56$
Subtract and Combine Terms: Now, subtract $7x$ from the result of the distribution. $\newline$ $28x + 56 - 7x$ $\newline$ Combine like terms ( $28x$ and $-7x$ ). $\newline$ $(28 - 7)x + 56$ $\newline$ $= 21x + 56$
Check for Accuracy: Check the original expression and the final simplified expression to ensure that no steps have been missed and that all operations have been performed correctly. $\newline$ Original expression: $7(4x+8)-7x$ $\newline$ Final simplified expression: $21x + 56$ $\newline$ No steps have been missed, and all operations are correct.
