First, we will distribute...

1+2a+(-3)(4)+(-3)(5a)+42+(6)(-8a) ---Simplify---

=1+2a-12-15a+42-48a ---Combine like terms---

=-61a-12+1+42

=-61a+31

Area of a trapezoid: A=((a+b)/2)*h where a and b are bottom and top side lengths, and h=height.

Now, we can just plug in the values!

((10+16)/2)*7.6

=(26*7.6)/2

=98.8

Hope this helped!

The formula for volume of a cylinder is: V=pi*r^2*h where r= radius, V=volume, and h=height

We can plug in these values to get the volume.

The equation we will get will be: V=7.6^2*2.3*pi

This will get us about 417.4

x=actual height of Nadia in inches

We know the formula for tan is (opposite side)/(adjacent side), so if we set the degrees to 60, it will represent the sun shining at a 60-degree angle.

x=tan 60 degrees*31------(Sunshine times Nadia's shadow)

Using a calculator, that will give us about 53.69, which would round to 54. 

Nadia is 54 inches tall.

Here's a simpler way to solve it.

First, make 37 1/4 into a mixed number: 149/4

Then, multiply it by 32.

(149/4)*32 (simplify)

(149/1)*8=1192
