Answer:
414cm^2
Step-by-step explanation:
Given data
Base a= 9cm
Hence the expression for the surface area is
SA=2a^2+4ah
A=2*9^2+4*9*7
A=162+252
A=414cm^2
Hence the surface area is 414cm^2
when x=-2
-10(-2)+y=4
y=4-20
y=-16
when x=-1
-10(-1)+y=4
y=-6
when x=0
-10(0)+y=4
y=4
when x=1
-10(1)+y=4
y=14
when x=2
-10(2)+y=4
y=24
