Take the square root of the entire thing for get rid of square, then solve for a
43.96
Explanation:
C=2pi(r)
C=2pi(7)
C=14pi
14 x 3.14 = 43.96
It is neccesary because you cannot subtract them without having a common denominator so you have to rename 4 1/2
Answer:
E (3,-1) D (-2, -2) G (-1, 3) F (3, 2)
Step-by-step explanation:
90 degrees = (y, -x)
that means you take the ordered pair you want to rotate and plug the x and y into the new spots.
for example, point E is at (1,3) so the point rotated 90 degrees is (3,-1)
