Question

Which expression has a value that is equivalent to 5n + 13 when n=−5 ?

4n + 8
n² + 13
n + 8
2n + 2

Answer 1

Answer:

Step-by-step explanation:

4n + 8

Answer 2

if n=-5
5n+13=5(-5)+13=-25+13=-12


4n+8=4(-5)+8=-20+8=-12
n²+13=(-5)²+13=25+13=38
n+8=-5+8=3
2n+2=2(-5)+2=-10+2=-8


therefore,4n+8=5n+13 ,when n=(-5)
