2x^2 + 8x - 24
Step-by-step explanation:
The formula for a trpezoid is (b1+b2)*h/2. If you substitute with the given domensions, you get
((2x + 12 + 4)*2x-4)/2
Simplify
((2x+16)*2x-4)/2
(4x^2+16x-48)/2
2x^2 + 8x - 24
Answer:
Step-by-step explanation:
x is the number of students
(x+5) is the number of students and chaperons
$2.50·(x+5) is the amount of money the number of students and chaperons will pay for the trip, and that number should be less or equal than $90 because those are all the money they have
2.50(x+5) ≤ 90 which is the same as 90 ≥ 2.50(x+5)
The inequality "90 greater-than 2.50 (x + 5) "
90 > 2.50(x+5) is an error becase it excludes the possibility that <u>the trip can cost exact $90</u> so we need not just greater than > , yet greater and equal than ≥ sign
90 ≥ 2.50(x+5)
