Given: f(x) = 2x + 5 and g(x) = x2 and h(x) = -2x h(g(f(x))) = Ax² + B + C

Which is A: 4, -8, 8
Which is B: 20,-20,-40
Which is C: 50, -50, 25

(2x+5)(2x+5)

4x^2+10x+10x+25

4x^2+20+25

A=4

B=20

C=25

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
