The square root of the left hand side is 2*(x - 1).The square root of the right hand side is 2*sqrt(14)
No but they are both quadrilaterals because they have 4 sides
In both shapes, all four sides are of equal length.
A square or a rectangle would both fit the given description.
-4x-4 equals -16. Add 4 to both sides; -4x equals -12. Divide both sides by -4; x equals 3.
2k - 1 = 0 Add 1 to both sides: 2k = 1 Divide both sides by two: k = 0.5
aN - bN = a - bN : add bN to both sides then aN = a : divide both sides by a N = a/a = 1
subtract 15 from both sides then divide both sides by -4. g=12
3p - 8 = 13 - 4p : Add 4p to both sides 7p - 8 = 13 : Add 8 to both sides 7p = 21 : Divide both sides by 7 p = 3.
6 - 7x = 24 - 21xSubtract 6 from both sides:- 7x = 18 - 21xAdd 21x to both sides:14x = 18Divide both sides by 14:x = 18/14 = 9/7
The = sign
-5 -15n = 10add 5 to both sides-15n = 15divide both sides by -15n = -1
Add 9 to both sides: 7c - 14 Divide both sides by seven: c = 2
