The browser used for posting questions on this site is mostly useless for mathematical questions since it strips out most symbols. It is, therefore, not possible to tell where the equality (or inequality) symbol in the function lies and so determine the domain or range.
The sum is 28x
68 + 28x - 28 = 236 28x + 68 - 68 -28 + 28 = 236 - 68 + 28 28x = 196 x = 7
.740
5x + 23x + 10 = 28x + 10( ? ? ? )
7x+7=28x 28x-7x=7 21x=7 x=3
49x2+28x+4 = (7x+2)(7x+2) when factored
The sum is 28x
68 + 28x - 28 = 236 28x + 68 - 68 -28 + 28 = 236 - 68 + 28 28x = 196 x = 7
what is -12X squared +28X - 15? i figured it out myself. its (-6X + 5)(2X - 3).
.740
5x + 23x + 10 = 28x + 10( ? ? ? )
7x+7=28x 28x-7x=7 21x=7 x=3
x=35
14x(x + 2)
It can be simplified to: 9-28x
4x2 + 28x + 49 = 4x2 + 14x + 14x + 49 = 2x(2x + 7) + 7(2x + 7) = (2x + 7)(2x + 7) or (2x + 7)2
4x(4x^2 - 6x + 7)
