Answer:

A = 3h^2 - 2h

Step-by-step explanation:

First lets find out what each of the bases is

b_{1} =h -4\\\\\\b_{2} =5h

Next, we can use the equation for the area of a trapezoid, which is

A=\frac{b_{1} +b_{2}}{2} h

Now we can plug in each of the values that we have for the bases and then solve for A.

A=\frac{ h-4 + 5h}{2}h\\\\A=\frac{6h-4}{2}h\\\\A = (3h - 2)h\\\\A=3h^2-2h

kirill115 [55]

Answer:

I'm pretty sure that the answer would be 229/236.

Step-by-step explanation:

Ok so. Since the results of the test is 229 for a girl and the results for a boy is 7. So i'm pretty sure what to do is combine both the results and keep that as the denominator. And then the numerator will be the result. So in this case the numerator would be 229 and the denominator would be 236.

I hope this helped, have a great day!!!
