Otto spent 3/4 of the money he had saved on a new video game. if the video game cost $48, how much money did he have before he bought the game?

$64

Step-by-step explanation:

Given: The part of money he spent =3/4

Let the total money Otto has be 'x'.

Then according to the question, we have

Multiply 4 on both the sides, we get

Divide 3 on both the sides, we get

Hence, the money he had  before he bought the game = $64

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
