which of the following equations represents the greatest value of x?

equation 1 – x^2 = 17
equation 2 – x^2 = 26
equation 3 – x^3 = 64
equation 4 – x^3 = 27

a. equation 1
b. equation 2
c. equation 3
d. equation 4

i think the x values are:
1- x= 4.12 or 4.12
2- x= 2
3- x= 4
4- x=3

i think it's a, but i need someone to look over it.

Arianna is buying plants for her garden. she buys 15 flowering plants for $96. pink flowering plants sell for $8, and purple flowering plants sell for $5. how many pink flowering plants did arianna buy? i figured out the answer! the answer is 7. 8x +5y = 96 plug in 7 for x 8 (7) + 5y = 96 56 + 5y = 96 subtract 56 from both sides 5y/y = 40/5 y = 8 she bought 7 pink and 8 purple plants

Simply 8x squared + 5(7x squared- x) - 2x =
