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: $3.70
Step-by-step explanation: To find unit price per, just divide total units by total price. So in this case dividing 14 ( total tangerines) by 3.78 ( total price paid) gives us the price per tangerine, which is $3.7037, or rounded to $3.70

4x=5x-4
-4x -4x
-1x=-4
x=4
