Answer:
Area of a trapezoid = ½(a + b)h, where a and b are the lengths of the parallel sides and h is its height.
From your information 20 = ½(2z + 3 + 6z – 1)z = ½(8z + 2)z = z(4z + 1)
Solve 20 = 4z² + z which is 0 = 4z² + z – 20 using the quadratic formula

Answer:
m>11
Step-by-step explanation:
2(m+3)<-5+3m
2(m+3)>3m-5
2m+6>3m-5
6<3m-5-2m
6<m-5
6+5<m
11<m
m>11

Answer:
uhh that's a negative decimal unsure what you want
There should be 480 visitors (including children)
This would be because 60% of the people have 180 children so divide by 6 and you have 30 or 10%, multiply the 30 by 10 (to get a hundred percent [300] ) and add the children to get 480.
