25=x
25 x 9 = (20 x 9) + (5 x 9)20 x 9 = 1805 x 9 = 45180 + 45 = 22525 x 9 = 225
9 sq m
25 = x x v06 = v i1993 = m c m x c i i i
The answer is: 9 m3 100 mm = 10 cm = 0.1 m so 22.5 X 4 X 0.1 = 9 m x m x m = m3
9 + 9 + 4.5 + 4.5 = 27 m
x = (-25) x/5 + 9 = 4 (multiply both sides by 5) x + 45 = 20 x = -25 Checking: (-25)/5 + 9 = 4 gives -5 + 9 = 4 correct
m = 9 This is because, if: m squared - 2m - 65 = 2 Then: m squared - 2m = 65 + -2 m squared - 2m = 63 So: 63 = m squared - 2m m squared - 2m = m x m - 2m This means: 63 = m (m - 2) So something times itself minus two is 63. Going through different numbers, it is clear that 9 and 7 work. So: m x (m - 2) = 9 x (9-2) = 9 x (7) = 9 x 7 = 63 M is therefore 9.
3 x 3 = 9 5 x 5 = 25
m/(-4) = 9m = 9 x (-4)m = -36
9m
25 x 9 = 225
