(x2 - 16) = (x + 4) (x - 4)
14 400 :)
x-14 = 20 x = 20+14 x = 34
4 x 4 x 4 x 4 x 4 = 45
The inequality sign is neglected due to the omitted punctuation for the question. Assume x + 8 ≤ 14. Then, subtract both sides to get: x ≤ 6. If x + 8 < 14, then x < 6. If x + 8 > 14, then x > 6. If x + 8 ≥ 14, then x ≥ 6.
-4-x = 10 -x = 10+4 -x = 14 x = -14
-4-x = 10 -x = 10+4 -x = 14 x = -14
56 or 84 56 = 4 x 14 = 7 x 8 = 14 x 4 84 = 4 x 21 = 7 x 12 = 14 x 6
6X + 4 = X + 14 subtract X from each side 6X - X + 4 = X - X + 14 5X + 4 = 14 subtract 4 from each side 5X + 4 - 4 = 14 - 4 5X = 10 divide each sides integer by 5 (5/5)X = 10/5 X = 2 ----------------check in original eqiation 6(2) + 4 = 2 + 14 12 + 4 = 2 + 14 16 = 16 ---------------------checks
The LCM (lowest common multiple) of 14 and 4 is 28.28 = 14 x 228 = 4 x 7
14
1 x 28, 2 x 14, 4 x 7, 7 x 4, 14 x 2, 28 x 1
1 x 28, 2 x 14, 4 x 7, 7 x 4, 14 x 2, 28 x 1
1 x 28, 2 x 14, 4 x 7, 7 x 4, 14 x 2, 28 x 1
7 / 8 x 4 / 14 7 x 4 = 28 8 x 14 = 112 28 / 112 same as 1 / 4
4/7 = 4/14 x 2
If x-4=10 then x=14.
