Answer:
2x^2 + 8x - 24
Step-by-step explanation:
The formula for a trpezoid is (b1+b2)*h/2. If you substitute with the given domensions, you get
((2x + 12 + 4)*2x-4)/2
Simplify
((2x+16)*2x-4)/2
(4x^2+16x-48)/2
2x^2 + 8x - 24

Answer:
f(x)=x+2 Passes through
x-y=2 DOES NOT pass through
Step-by-step explanation:
Method- plug in x and see if the y matches the points. (1,3) (7,9)
f(x)=x+2
f(1)=1+2=3
f(7)=7+2=9
Matches!
x-y=2
1-y=2 --> y=-1
Does not match
