All the corners of a rectangle is equal to 90 degrees. So you need to set (x-1) and (2x+10) equal to 90 and then solve for x. 

(x - 1) + (2x + 10) = 90
<em>Combine the like terms...
</em>3x + 9 = 90
<em>Subtract both sides by 9...
</em>3x + 9 - 9 = 90 - 9
3x = 81
<em>Divide both sides by 3...
</em><em>3x = 81
</em>(3x) / 3 = 81 / 3
x = 27

Does anybody know how to solve for “C”?.
Jobisdone [24]

Answer:

c = (b+3a)/2

Step-by-step explanation:

<u>Solve for c:</u>

  • 1/ac = 2/ab - 3/bc

<u>Multiply both sides by abc:</u>

  • abc/ac = 2abc/ab - 3abc/bc
  • b = 2c - 3a
  • b + 3a = 2c
  • 2c = b + 3a
  • c = (b + 3a)/2

2x^3-3x^2-11x+6 divide by x-3
Alexxx [7]

Answer: 2x^2+3x-2

Step-by-step explanation:

You can do long division, which is very very hard to show with typing on a keyboard. You essentially want to divide the leading coefficient for each term. Ill try my best to explain it.

Do \frac{2x^3}{x}=2x^2. Write 2x^2 down. Now multiply (x - 3) by it. Then subtract it from the trinomial.

2x^2*(x-3)=2x^3 -6x^2\\(2x^3 -3x^2-11x+6)-(2x^3-6x^2) = 3x^2-11x+6

Now do \frac{3x^2}{x} =3x. Write that down next to your 2x^2. Multiply 3x by (x - 3) to get:

3x(x-3)=3x^2-9x\\(3x^2-11x+6)-(3x^2-9x)=-2x+6

Your final step is to do \frac{-2x}{x} =-2. Write this -2 next to your other two parts

Multiply -2 by (x - 3) to get:

-2(x-3)=-2x+6\\(-2x+6)-(-2x+6)=0

Our remainder is 0 so that means (x - 3) goes into that trinomial exactly:

2x^2+3x-2 times
