Three times the square of a number is 6 more than
twice the number. What is the number?

Given that,

Three times the square of a number is 6 more than

twice the number

Therefore,

3x² = 2x + 6

3x × x = 2x + 6

x = 2x + 6

3x

x = 2x + 6

3x 3x

x = 2 + 6x

3 3x²

x = 2 + 2x

3

x - 2x = 2

-x = 2

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
