PLEASE HELPPP!! Emily collects and trades rocks. She starts with 8x^2 rocks, for some number x, and then buys 7x^4. She then trades away x^5, then gives away 9x, and finally sells another 5 rocks. Write an expression for the number of rocks Emily now has in standard form. A. −9x + 8x^2 + 7x^4 − 5 − x^5

B. 8x^2 − 5 + 7x^4 − 9x − x^5

C. −x^5 + 7x^4 + 8x^2 − 9x − 5

D. −5 − 9x + 8x^2 + 7x^4 − x^5

The label on the car's antifreeze container claims to protect the car between ? 40°c and 125°c. to convert celsius temperature to fahrenheit temperature, the formula is c = 5 over 9 (f ? 32). write and solve the inequality to determine the fahrenheit temperature range at which this antifreeze protects the car. ? 40 > 5 over 9 (f ? 32) > 125; ? 40 > f > 257 ? 40 < 5 over 9 (f ? 32) < 125; ? 40 < f < 257 ? 40 < 5 over 9 (f ? 32); ? 40 < f 5 over 9 (f ? 32) < 125; f < 257
