Which equation is an identity? O 3(- 1) =r=2(x + 1) + 1
O x-4(x + 1) = -3(x + 1) + 1
O 2x+3= 1(4x+ 2) + 2
03 (6x – 3) = 3(x + 1)-x-2

If x = -2, then x 2-7x+10 equals a. 0 b.20 c.28

In triangle △abc, ∠abc=90°, bh is an altitude. find the missing lengths. ac=26 and ch=8, find bh.

Point a is at 12, and point d is at 56. point c is midway between a and d, and point b is midway between a and c. which of these is the coordinate of b?
