1. C (x+8)^2
2. D y=6^x
3. D t/2.35 ; 2.13 ft.
4. A (7h^2-2h)/2; 672 cm^2
5. A 4.50 h ; $7.88
For one and two you just have to plug in the numbers into the equation to see what works.
Three four and five you have to read the problems and come up with an equation to get your answer. Please comment if you need to see the work!
Answer:
see explanation
Step-by-step explanation:
A
given
= 
( cross- multiply )
5.7f = 34.2 ( divide both sides by 5.7 )
f = 6
-----------------------------------------------------
B
given
= 
( cross- multiply )
3.6g = 92.34 ( divide both sides by 3.6 )
g = 25.65
4x+8 = 32, 4x = 24, x = 6
