(x2 - 16) = (x + 4) (x - 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).
Multiply first equation by 2: 4x - 2y = 20 Subtract second equation: x = 12, so y = 14.
You seem to be unaware of the fact that you could have obtained the answer much more easily and quickly by using the calculator that comes as part of your computer. 14 + 14 = 28.
5 to the 7th power times 13
6 and 14? Is that plus or minus or times or divided by or separate or what?
Yes, 14 to the second power or 14 squared, equals 196.
2 and 14 are factors of 28.
The GCF is 14.
fourteen to the second power = 196
14 to the power of 8 AKA 14^8
The factors of 28 are 1,2,4,7,14 and 28. 14 is the second largest. For any of them to be common, they need to be compared to another set of factors.
142 = 196
