Which of the following is the general form of the equation 5x 2 - 20x = 15?
x 2 - 4x = 3
x 2 - 4x - 3 = 0
5x 2 - 20x - 15 = 0

x^2 - 4x - 3 = 0

The volume of a rectangular prism is equal to x^3 + 4x^2 + 3x.
What is the longest edge of the prism?
**Weegy:** 3x + 2y = 11, y = 4x --> 3x + 2(4x) = 11 --> 3x + 8x = 11 --> x = 11/11 = 1 **User:** Factor the four-term polynomial.

Factor the four-term polynomial.
mn - 15 + 3m - 5n
**Weegy:** mn-15+3m-5n
Let's rearrange the terms
mn + 3m - 15 - 5n
= m*(n + 3) - 5(n + 3)
= (m - 5)(n + 3)
**User:** Factor completely.
49t^6 - 4k^8
**Weegy:** 49t^6 - 4k^8 = (7t³ + 2k^4)(7t³ - 2k^4) (More)
