Hello,
one of two<span> fixed points inside an ellipse from which the </span>sum<span> of the </span>distances<span> to any point on the ellipse is constant. </span>
Volume = 12 * area of triangular base
area of triangle = 1/2 base * height = 3 * height
height = sqrt(5^2 - 3^2) = 4
area of triangle = 4*3 = 12
Vol of prism = 12*12 = 144 cubic units
3.35 - 3.10 = .25
.25/3.35 = .0746
.0746*100 = 7.46 or 7.5 rounded
Ok so the answer is

so we multiply numbers that have the same variable

multiply 2 x 2

then multiply the exponents

multipling like this will look like addition.

so in other words you could do it like this too

now add the exponent with 4

now for the last part

because -3 and 3 added together make 0

I hope this help(it looks complicated but it's very easy and I hope I helped you out)
