Answer:

Step-by-step explanation:

A number squared also means that the number is multiplied by itself twice.

Answer:
there needs to be at least 77 cakes sold
Step-by-step explanation:
let 'c' = # cakes sold
3.25c ≥ 250
c ≥ 250÷3.25
c ≥ 76.9
To get rid of

, you have to take the third root of both sides:
![\sqrt[3]{x^{3}} = \sqrt[3]{1}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7Bx%5E%7B3%7D%7D%20%3D%20%5Csqrt%5B3%5D%7B1%7D%20)
But that won't help you with understanding the problem. It is better to write

as a product of 2 polynomials:

From this we know, that

is the solution. Another solutions (complex roots) are the roots of quadratic equation.
Answer:
787.50
Step-by-step explanation:
interest=principle*rate*time/100
interest=3500*7.5*3/100
interest=35*7.5*3
interest=787.50
