Question

what is the algebraic expression for:
1. 4 times a number cubed decreased by 7

2. 3 more than 5 times the number

3. 15 less than a number squared

4. The product of 5 and y added to 3

Answer 1

I wrote the algebraic expressions in order for you. When I show the up arrow, it represents that the number after the arrow is an exponent. Hopefully this helps. :D

4 • (n^3 - 7)

(5 x n) + 3

(n^2) - 15

3 + (5 x y)
