Which of the following represents the factorization of the trinomal below
Ira Lisetskai [31]
X^2 - x - 20
(x + 4)(x - 5) <==

x^2 - x - 20.....the last sign, which is negative, tells me that one set is positive and one set is negative. The first sign, which is also negative, tells me that the larger number will be negative. Now u have to find 2 numbers, that when added equal -1 and when multiplied, equal -20....those numbers are -5 and 4. so ur answer is : (x + 4)(x - 5)

Answer:

Hey there!

We don't have enough information. 7(n+5) can be written as either the 7 times the sum of n+5, or 7 multiplied by n+5.

Let me know if this helps :)

  2. Isolate <em>x</em>:                                        x = 4

<u>Step 3: Solve for </u><em><u>y</u></em>

  1. Define equation:                   -x + 4y = -8
  2. Substitute in <em>x</em>:                      -4 + 4y = -8
  3. Isolate <em>y</em> term:                       4y = -4
  4. Isolate <em>y</em>:                                y = -1
