Find the perimeter of parallelogram ABCD with vertices A(–5, 6), B(2, 6), C(1, –2), and D(8, –2).

zavuch27 [327]

Since in A and B we have the same y value, 2-(-5)=7 and that's one side. For A to C (we connect A to C since they are both the ones on the left), we use the distance formula to get sqrt((-5-1)^2+(6-(-2))^2=sqrt(36+64)=sqrt(100)=10. Since there are 2 equal pairs of sides in a parallelogram, we get 7*2+10*2=34

Using long division to find the quotient and remainder 4x^4+2x^2-2 divided by x^2+2

emmasim [6.3K]

4x² -6
__________________
x²+2 l 4x^4 +2x² -2
l 4x^4 +8x²
--------------------
-6x² -2
-6x² -12
---------------
10

so the answer is $(4x^2-6) \frac{10}{x^2+2}$
