Draw a right rectangular prism. Draw it so one face is pretty much the way you would see it if it was real. The other two faces you can see have a slant to them.

Label the face you can see as x and y. Name any of the slanted lines as z. Put cm for centimeters behind the letters.

Volume = x*y*z the units here are cm^3
Why because you are multiplying cm*cm*cm together.

The surface area is a whole different ball game.
you have 2 surfaces who have areas of x*y There's one in front of you and one you cannot see
You have a top and a bottom that is y*z each that's 2y*z

You have two surfaces that are x*z each and that's 2x*z

The total surface area = 2xy + 2xz + 2yz
The units here are cm*cm or cm^2

Given the isosceles trapezoid below, find AG.<br> Show all the work
Dmitry [639]

We know the width of the rectangle in the middle of the trapezoid is 24 (from the top of the image), so we can subtract that from the bottom width of the trapezoid to get the combined length of the bottom of both triangles.

40 - 24 = 16

Since this is an isosceles trapezoid, both triangle bases are the same length, so we can cut this value in half to get the length of GT and EF

\frac{16}{2} = 8

Finally, we can use the Pythagorean Theorem to find the length of AG:

AG^{2} + GT^{2} = AT^{2}

AG^{2} + 8^{2} = 10^{2}

AG^{2} + 64 = 100

AG^{2} = 36

AG = 6

9t - 3t + 4
= 6t + 4

(hence 9-3)

you can do this due to the t being the same unit (classified as a like term). if it were 9t - 3g + 4, it would have to stay the same.

Write an equation of the line that passes through a pair of points:<br> (-3,1). (-2,-5)
Nat2105 [25]

Answer:

y=-6x-17 (B)

Step-by-step explanation:

y=mx+b\\m=\frac{y_{2}-y_{1}  }{x_{2} -x_{1} } = \frac{1--5}{-3--2} = \frac{6}{-1} = -6\\y=-6x+b\\

Plug in one of the two points for X and Y

(-3,1)

1=-6(-3)+b\\1=18+b\\b=-17\\\\y=-6x-17
