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

D. He forgot to subtract the area of the base from the total surface area of the  cube.

Hope this helps. :)

What is the probability of rolling a product of 30 when rolling two dice?
Nimfa-mama [501]
It has a probability of 2 out of 36 chances as there are only two ways it can happen out of 36 different combinations that can be rolled. Product means multipication also in Maths 

<span>The first probability on the first roll is that Dice 1 must be a 5 and Dice 2 must be a 6 so that 5x6=30 </span>

<span>The second probability on the second roll is that Dice 1 must be 6 while Dice 2 must be 5 so that 6x5=30 </span>

<span>That is the only two ways out of 36 different combinations that can be made by rolling to Die. Therefore the probability is 2 out of 36
