A cell phone costs $448, a battery charger costs $14, and batteries cost $7. What is the sales tax and total price for purchasing these items if the sales tax rate is 6%

Add all 3 costs to find the total cost before taxes.

448 + 14 + 7 = $469

Turn the percentage into a decimal.

6% = 0.06

Multiply the sales tax to the total cost.

0.06 * 469 = $28.14 (sales tax)

Add to the total price.

469 + 28.14 = $497.14 (total price after taxes)

Best of Luck!

step-by-step explanation:

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)
