Rewrite in simplest terms: 2(-10 r+r-2)-8r Answer:

Distribute Terms: Distribute the 2 across the terms inside the parentheses. We need to multiply each term inside the parentheses by 2. Calculation: 2 * (-10r) + 2 * r + 2 * (-2) = -20r + 2r - 4Combine Like Terms: Combine like terms within the expression. We have -20r and 2r which are like terms and can be combined. Calculation: -20r + 2r - 4 = -18r - 4Subtract 8r: Subtract 8r from the result obtained in Step 2. Now we subtract 8r from -18r - 4. Calculation: -18r - 4 - 8r = -26r - 4

Q. Rewrite in simplest terms:

2(-10 r+r-2)-8 r

\newline

Answer:

Distribute Terms: Distribute the $2$ across the terms inside the parentheses. $\newline$ We need to multiply each term inside the parentheses by $2$ . $\newline$ Calculation: $2 \times (-10r) + 2 \times r + 2 \times (-2)$ $\newline$ = $-20r + 2r - 4$
Combine Like Terms: Combine like terms within the expression. $\newline$ We have $-20r$ and $2r$ which are like terms and can be combined. $\newline$ Calculation: $-20r + 2r - 4$ $\newline$ $= -18r - 4$
Subtract $8r$ : Subtract $8r$ from the result obtained in Step $2$ . $\newline$ Now we subtract $8r$ from $-18r - 4$ . $\newline$ Calculation: $-18r - 4 - 8r$ $\newline$ = $-26r - 4$
