Answer:
25:26,28,30
26:-4,-2,0
27:W=V/LH
28:(A-PH)/2
Explanation:
25: The first thing you need to do is 84/3=28, which is in the middle. On the left side, it should be 28-2, which is 26, and on the right side, it should 28+2, which is 30, so the answer is 26,28,30.
26: The first thing you need to do is -6/3 = -2, which is in the middle. On the left side, it should be -2-2, which is -4, and on the right side, it should be -2+2 which is 0, so the answer is -4,-2,0.
27: V=LWH, W=V/LH.
28: A - PH = PH + 2B - PH, A - PH = 2B, (A - PH)/2 = 2B/2, B = (A - PH)/2.
