Please help me, I don’t understand!!

F(x) also means substitute the x

Not rly sure about g(x) but a teacher told me it is almost the same because it is just substitute.

F(x)=2x^2+6x-8

G(x)=-3x-3

So substitute 1 to the x’s

2(1)^2+6(1)-8

-3(1)-3

I will solve the first one first then next

2(1)^2+6(1)-8

First multiple

2+6-8

Next just solve that

ANWSER ONE IS ZERO

Next

-3(1)-3

Multiple

-3-3

Just solve it

ANWSER TWO IS -6

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
