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)
= (n+3)*(m-5) User: Factor completely.

What is the solution set of 7x^2 + 3x = 0?

Weegy: First you will want to take the 5 and multiply it to the -3X and 4 so it will look like this:
7X -15X-20=-21-7X Got it?
Then you will combine the X's on the first side so you will get this:
-8X-20= -21-7X
Next you need to get the X's on [ [ [ one side so you will take the one that is less, in this case -8X and add it to the -7X. When it crosses over the equal mark it becomes a positive so you will get this next:
-20=-21 + X ... (More)
