11. the winning swim team camned 245 points. the other teams earned at least

72 points less

a. write an inequality that represents the points that the other teams earned.

b. was one of the teams able to earn 180 points? explain.

me solve this

A

B. No

Step-by-step explanation:

The winning swim team camned 245 points.

The other teams earned at least 72 points less, this means the other teams earned 72 points less, or 73 points less, or 74 points less, ...

The greatest number of points the other teams earned is

245 - 72 = 173 points

A. Let x be the number of points the other teams earned. So, the inequality that represents the points that the other teams earned is

B. The winning team earned 245 points (not 180 points). Each other team earned 173 points or less, so there are no teams which earned 180 points.

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)
