Differentiate each function. do not expand an expression before differentiating.
a)f(x)=(2x+3)^4

Determine the difference: 3.2 × 1010 – 1.1 × 1010. write your answer in scientific notation.

2x minus y equals 6, x plus y equals negative 3

When solving this problem: 3025/5.5 = a/90.75 you get 49912.5 which would be the length of one of the sides of a square when the area is only 90.75 inches. is that answer correct, why, and how is it possible?
