Add the expressions: 9(20m - 5) + (m +7)

Hey there!

9(20m – 5) + (m + 7)

DISTRIBUTE

9(20m) + 9(–5) + m + 7

9(20m) + 9(–5)

9(20m) = 180m

9(–5) = -45

NEW EQUATION: 180 – 45 + m + 7

COMBINE your LIKE TERMS

(180m + m) + (–45 + 7)

“m” itself is understood as an invisible 1!

180m + m = 181m

–45 + 7 = –38

NEW EQUATION: 181m – 38

ANSWER: 181m – 38 ☑️

Good luck on your assignment and enjoy your day!
