Answer:
f(x)=3x+2,g(x)=2x^(2)-1
Step-by-step explanation:
First set up the composite result :
f (g (x))
Evaluate f (g (x))
3( 2x sqaured -1 ) + 2
Simplify:
f ( 2X SQUARED -1 ) 6 x squared -3 + 2
Add 2 and -3
It would be 12x because 9x and 3x are like terms :)
13/20= 0.65
3/4=0.75
4/10=0.4
5/8=0.625
So the right order is 4/10, 5/8, 13/2, 3/4
In this question, AE is the length of half of one diagonal in the rectangle. DB is the length of the other diagonal. 2(4x-12) would be the total length of the other diagonal, AC. You can set 2(4x-12) equal to 7x-18 and solve for x.
2(4x-12)=7x-18
8x-24=7x-18
x-24=-18
x=6
