Find the sum 2n^3 +4n^2-7 and -n^3-8n-2

Step-by-step explanation:

The only thing that you have to do is to add the different terms that have the same exponent and the same algebraic term.

=

-8n

-7 -2= -9

After adding up the different terms:

if you're trying to figure out how much each ounce cost it would be 0.20

cents each ounce

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough
