Step-by-step explanation:
y=mx+c
-4=6(12)+c
-4=72+c
-4-72=c
c=-76
y=mx+c
y=6x-76
1a= (2x+5)+3x+15
1b= (2(4)+5)+3(4)+15=40
2a= (3x+5)•(4x-3)
2b= (3(2)+5)•(4(2)-3)=55
2c= 2(x) or 2(2)
How I got 2c is the perimeter of the rectangle LMNP subtract from (2(2)+9)+(2(2)+9)=26 which in return means you subtract 30 from 26 and get 4 which is 2(2) or 2x
I think that the answer is A.
