Your total cost with tax is $29.51, including 7% sales tax. What is the price without the tax?

Step-by-step explanation:

Make an equation first.

29.51=1.07 (x)

The 29.51 is after the 7% sale tax, so we are trying to figure out the original price.

After you make the equation, you solve the 1 step equation.

Divide both sides by 1.07 to get the answer.

27.57944=x

So you woyld want to round this answer to get $27.58

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6

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)
