On Monday, Wilbert did 20 push ups in a minute, took a 30 second rest and was able to complete a few more push-ups. He ended his Monday work out after 30 total pushups. On Friday, Wilbert did 25 push ups in a minute. He did a couple more after a 30 second break and ended his Friday with 40 push-ups. On what day did Wilbert experience a smaller percent change of push-ups? set up the problem (include units)

explain please

​

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)

im guessing (23,14). hope this : )
