You can buy 3 t-shirts for $24. write a proportion that gives the cost c of buying 7 t-shirts.

$56

Step-by-step explanation:

Divide 24 by 3 to get 8

$8 will be the amount it'll cost for 1 t-shirt

So you would multiply 7 by 8 to get 56

So $56 will be the amount of 7 t-shirts

my guess would be b and d, but i didn’t actually get out the pen and paper. lol

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)
