They want you to factor using the AC method. If you are familiar with this, it means to label the coefficients.

This means that 4 is a factor so you can rewrite

Last one :)
Step-by-step explanation:
Answer:
take a look at the explanation
-u divided by h
Ei = 9r......E = (9r)/ i
i = 18
r = 5
now we sub
E = (9 * 5) / 18
E = 45/18
E = 2.5......the pitchers ERA is 2.5
