PLEASE HELP due at 8 am

x=10

y=170

Step-by-step explanation:

(6x-18)=42

6x=42+18

6x=60

x=60/6

x=10

To find y

180-10=170

y=170

third option: 6x+8

step-by-step explanation:

we can see that the given question is a sum of series and the values of n vary from 0 to 3

the first term will be:

when n=0, [(0)*x+2] => (0+2) => 2

when n=1, [(1)*x+2] => (x+2) => x+2

when n=2, [(2)*x+2] => 2x+2

when n=4, [(3)*x+2] => 3x+2

so adding up all the terms will give us:

=2+x+2+2x+2+3x+2

=x+2x+3x+2+2+2+2

=6x+8

so,

third option is the correct answer ..

x^6

step-by-step explanation:

this is correct because:

x-6=0

0*x=0

so

x^6
