Answer:
Step-by-step explanation:
I'm going to write it so I can see it better:
You can use the difference of squares formula:
13.5 bc x equal 2.7 so you multiply it by 5
A function intercepts the y line, when x is equal to 0. So we insert x=0 and get:
to solve this you will first subtract 8 from 84
you will get 76
now all you do is divide 76 by 4 and you will get 19
if you dont know what divideing is you can just subtract 4 from 76 until there is only 0 left
the answer is 19 if you forgot
