Verona is an artist in Marfa, Texas, who paints the Marfa lights over a field. She prints postcards of her paintings to sell to tourists. The cost to print postcards is a
flat $60 fee plus $0.25 per postcard. She sells the postcards for $1.25 each. Write an
equation that represents Verona's costs and an equation that represents her
earnings on sales. How many postcards must she sell before she starts making
a profit?

what's that

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)

good luck on ur quiz test or homework. have a good day : )
