If that's -144, the answer is (5x + 12)(5x - 12)
5x
5x squared plus 33x plus 18 = (5x + 3)(x + 6) x = -6, -3/5
x^2 -5x-6 factors to: (x-6)(x+1)
(x - 4)(x + 9)
x = 8y = 6(5x8) + (3x6) = 58(5x8) - (3x6) = 22
95
5x + 2 = 22 5x = 22 - 2 5x = 20 5x/5 = 20/5 x=4
If: 10x+7 = 5x+22 Then: 10x-5x = 22-7 And: 5x = 15 So: x = 3
25xy is an equivalent expression.
If you want an even-sized pieces, you can make a 7-slice pizza. Otherwise, the maximum is 22. (.5x^2 + .5x + 1 is the formula to determine the maximum number of slices if you use "x" cuts.)

5x+8=6 5x=6-8 5x=-2 x=-0.4 Absolute value of -0.4=0.4
I presume that you mean 5x + 3y + 20 = 0 and 2x - y - 14 = 0. First put the formulae in the form y = mx + c. 3y = -5x -20 y = -5/3 x -20/3 and y = -2x + 14 Substitute the second formula into the first -2x - 14 = -5/3 x -20/3 -6x - 42 = -5x - 20 -42 = x - 20 x = -22 Substitute into equation y = -2x + 14 y = -2 x -22 + 14 y = 44 + 14 y = 58 Therefore the two lines meet at point (-22, 58).
3/5x + 22 = 28 To solve this: Subtract 22 from both sides: 3/5x = 6 Multiply by 5x: 3 = 6*5x Divide by 6: 3/6 = 5x Divide by 5: (3/6)/5 = x Work it out: 3/6 = 0.5 0.5/5 = 0.1 x = 0.1
It is a linear equation in the variable x. You can solve for x using algebra: -5x + 3 = -22 -5x = -25 -x = -5 x = 5
