Ray ML and MN are perpendicular. ray MP ia an angel bisector. find the value of x .

bulgar [2K]

Answer: x = 15

Step-by-step explanation:

First, we will have to acknowledge that Angle M is a complementary angle (that means that it is 90 degrees) meaning that 2x° + 4x° will equal 90 degrees. So, let’s set up this equation.

90 = 2x + 4x

90 = 6x

$\frac{90}{6}$ = $\frac{6x}{6}$

15 = x

Therefore, the x is 15.

What is the coefficient of the second term of the trinomial?

marin [14]

The coefficient of the second term is 18.

What you do is you FOIL the terms:
$(3x+3)(3x+3)\\ Multiply\ the\ first\ terms\ together:\\ 3x*3x=9x^{2}\\ Then\ the\ outer\ terms:\\ 3x*3=9x\\ Next,\ the\ inner\ terms:\\ 3x*3=9x\\ Finally,\ multiply\ the\ last\ terms:\\ 3*3=9\\ Putting\ the\ terms\ together:\\ 9x^{2}+9x+9x+9=9x^{2}+18x+9\\\\ Since\ (3x+3)^{2}=9x^{2}+Bx+9=9x^{2}+18x+9,\ then \ B=18.$
