Hey there!
“Simplify 3(5a + b) + 4(a + 2b)”
FIRST you have to DISTRIBUTE
3(5a + b) + 4(a + 2b)
3(5a) + 3(b) + 4(a) + 4(2b)
3(5a) = 15a
3(b) = 3b
4(a) = 4a
4(2b) = 8b
“15a + 3b + 4a + 8b”
SECOND: COMBINE your LIKE TERMS
(3b + 8b) + (15a + 4a)
(3b + 8b) = 11b ⬅️ BACK number
(15a + 4a) = 19a ⬅️ FRONT number
ALL OF YOUR TERMS/NUMBERS ARE POSITIVE SO WE DON’T HAVE TO FIX ANYTHING
Answer: C. 19a + 11b ☑️
Good luck on your assignment and enjoy your day!
