HELP ASAP WILL GIVE 100 POINTS.<br> Solve for x. <br><br> 89(54x−36)+2=−34(−40+16x)+90x
PolarNik [594]

Solution:

<u>Simplify the equation and solve.</u>

  • 89(54x − 36) + 2 = −34(−40 + 16x) + 90x
  • => 4806x − 3204 + 2 = 1360 - 544x + 90x
  • => 4806x = 1360 - 454x + 3202
  • => 5260x = 4562
  • => x = 4562/5260 = 2281/2630

The solution to the problem is 2281/2630.

How do you factor the trinomial 3x^2+18x-21?
snow_lady [41]

Answer:

(3)(x+7)(x-1)

Step-by-step explanation:

3x^2+18x-21

Let's start by taking 3 out of the equation.

3(x^2+6x-7)

Now, when we factor, we need to find two numbers that add up to 6 and multiply to -7.

The numbers would be 7 and -1.

So the factored form of this would be:

(3)(x+7)(x-1)
