Given quadrilateral EFGH with vertices at E(-4, 8), F (8, 4), G(5, -5 ) and H (-7, 1) , prove using coordinate geometry that EFGH is a rectangle. Note that there are a few different methods that work.

the equivalent expression are always the hardest ones but you look at the gcf also

step-by-step explanation:

what

faster, im not sure why but i know it is faster

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
