Answer :
Answer:
A. x + 27
Step-by-step explanation:
4(x+3)+3(5−x)
4x + 12 + 15 - 3x
x + 27
4(x + 3) + 3(5 - x)
First multiply each of the brackets by the number on the outside:
4(x + 3) = 4x + 12
3(5 - x) = 15 - 3x
Then add these into the expression:
4x + 12 + 15 - 3x
Collect the like terms (the things that have the same letters):
4x - 3x = 1x (but remember we don’t write the 1, so it’d just be x)
12 + 15 = 27
Therefore:
x + 27
Your answer would be:
A) x + 27
