The answer is
A. D<span>O, 0.75</span> (x,y) = (0.75x, 0.75y<span>)
B. </span>LM<span> is parallel to </span>L'M'<span>.
and C. </span><span>The vertices of the image are closer to the origin than those of the pre-image.</span>
64 m^2 - 9 n^2 -------(1)
first think about squares
what is 64 m^2 = ( 8m)^2
also what is 9n^2 = (3n)^2
so 64 m^2 - 9 n^2 = (8m)^2 - (3n)^2
= (8m -3n) (8m+3n) ------(2)
to check multiply (2) to get (1)
If you would like to find the average of 132 1/2 and 137 2/3, you can calculate this using the following steps:
<span>132 1/2 = 265/2
137 2/3 = 413/3
</span>
132 1/2 + 137 2/3 = 265/2 + 413/3 = 795/6 + 826/6 = 1621/6
<span>1621/6 / 2 = 1621/12 = 135 1/12
</span>
The correct result would be <span>135 1/12.</span>

(2 to the 10th power) is just a shorthand for <em>"10 2's mutliplied together."</em>
Say we had

. That would be 2 twos multiplied together, which is 4.

would be 8,

would be 16...
I LOVE MATH! And uh, its 22. I think I don't know.
