Matthew is 7 years older than twice the age of his sister. If Matthew is 13, how old is his sister?
A:3
B:4
D:10
C:33

Step-by-step explanation:

The answer is 33 because

If Mathew is 13 then twice is 13 x 2 = 26

Then 7 years older so 26 + 7 = 33

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
