Answer:
(f-g)(x) = (3(x+2)-1)(x)
This would equal (-3x-6)(x)
-3x^2-6x
Step-by-step explanation:
Q.1 a²+10a+24
splitting the middle.
a²+6a+4a+24
=a(a+6)+4(a+6)
(a+6)(a+4)
Q.2 x²+9x+18
splitting the middle
x²+6x+3x+18
x(x+6)+3(x+6)
(x+6)(x+3)
SSS congruence theorem.
We have proved that the 3 sides of the triangles are congruent.

first it goes up by 10 then 5 now 10
