Thomas bought 4 shirts from a store. the price of each shirt was the same. after he bought the shirts, his account balance showed a change of −$89.08. what would have been the change to thomas's account balance had he bought only 1 shirt from the store?

Step-by-step explanation:

a change of - 89.08 means that the total of all 4 shirts was 89.08.

that means that each shirt cost : 89.08 / 4 = $ 22.27

so his account balance would be : - $ 22.27 <=== dont forget the negative sign

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6

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)
