Answer:
The answer is 6
Step-by-step explanation:
A=½(b1 + b2) h
we substitute
Area=75
the two bases are 10 and 15
75=½(10+15) h
75=½(25)h
75=(1*25/2)h
75= 25h/2
75/1= 25h/2
25h*1= 75*2
25h= 150
we divide by 25
25h/25= 150/25
h=6

Answer:
40
Step-by-step explanation:
The formula for area is LxW, in this case it’s 5x8 which is 40.
Multiplication was invented to reduce the work involved in repeated addition.

352 passengers are carried <em>to</em> the island each day.
_____
Some questions must be answered before we can give a definite answer.
1. If the same person rides twice, are they counted twice?
2. Are passengers on the return trips (<em>from</em> the island) counted?
3. If return trip passengers are counted, is the ferry full on those trips?
4. Does every passenger to the island return the same day?
5. Does any passenger go to the island more than once per day?
Grayson's mistake was that he multiplied 4 and 3 and then used the exponent he had to square 3 and then multiply it by 4.
Emily's mistake was that she added 2 to 36 instead of multiplying it by -2
Pat's mistake was that he forget to make y into -2 instead of 2
The right way to do this is 4(3^2)+2(-2)
(3^2)=9 9×4=36 2(-2)=-4 -4+9=5
