Answer 1

Answer:

9. 4x + 5 = 32

10. x^2 - 4 = 12

11. (3 x 4) + x = 20

Step-by-step explanation:

Less than = -

Sum = +

A number = x

the square = x^2

The product = multiplication

More than a number = +

Is equals =

Answer 2

Answer:

• See below

Step-by-step explanation:

The unknown number is reflected as n.

#9

The sum of 5 and four times a number is 32:

• 5 + 4n = 32

#10

Four less than the square of a number is 12:

• n² - 4 = 12

#11

The product of 3 and four more than a number is 20:

• 3*(n + 4) = 20
