1-38 At the farmers’ market, two pounds of peaches cost $4.20. How much will five pounds cost? plz I need help!

$10.50

Step-by-step explanation:

If 2 pounds of peaches costs $4.20 then you would divide by 2 to find how much 1 pound costs. After I divided I got $2.10. $8.40 is 4 pounds. If we add one more we get 5. So add $2.10 to $8.40 and you get $10.50. Hope this helps! <3

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)
