Question

PLEASE HURRY!!!!!!!
Simplify using the distributive property.
5(n-3)=

A. 5n - 3
B. 5n + 15
C. 5n - 15
D. n - 15

Answer 1

First off, in 5(n-3), there would be a hidden multiplication symbol:

5(n-3)
=5 x (n-3)

We then need to multiply 5 by the numbers in the bracket seperately:

5×(n-3)
=5×n + 3×5
=5n + 15

Therefore the answer is C. 5n - 15.

Here's another example similar to the above case:

3(y-1)
=3 × (y-1)
=3 × y + (-1) × 3
=3y + -3

Hope it helps!
