Hey there!

5x - 7x^2 - (2x)^2

= 5x - 7x^2 - 4x^2

COMBINE the LIKE TERMS

(5x) + (-7x ^2 - 4x^2)

= -7x^2 - 4x^2 + (5x)

= -11x^2 + 5x

Therefore, your answer is: -11x^2 + 5

Good luck on your assignment and enjoy your day!

Help me with number 8

kirza4 [7]

Supreme sold 29 tires. Set it up like this, with Supreme as your x and Prestige as y: 48x + 56y = 2008. This is an equation in terms of money, with x being the number of Supreme tires sold at $48 each and y being the number of Prestige tires sold at $56 each. We know that Prestige sold 11, so sub it for y and do the math: 48x = 2008 - 616; x = 29
