Combine like terms:

subtract x from both sides to get

2x+5=14

subtract 5

2x=9

isolate x:

divide 2 from both sides to isolate x

x=9/2

that's your final answer. unless your teacher wants you to put it in decimal form in which all you do is divide 9÷2.

We can find roots by setting f(x) = 0 --> x^4 - x^3 - 13x^2 + x + 12 = 0.

Factoring f(x) to make things easier for us gives us (x - 1)(x + 1)(x - 4)(x + 3), which, equal to 0, gives us the ability to set each set of parentheses = 0.

x - 1 = 0 gives us x = 1.

x + 1 = 0 --> x = -1.

x - 4 = 0 --> x = 4.

x + 3 = 0 --> x = -3.

our roots are x = 1, -1, 4, and -3.

**Step-by-step explanation:**

10/30

hope this helps.............

It would be: 360- (101+133+76)

360-310 = 50 degree

**Answer:**

cos 30

**Step-by-step explanation:**

cos 30 + sin 60 / 1+ sin 30 + cos 60

= root3 / 2 + root3/2 / 1 + 1/2 + 1/2

= root 6/2 by 4/2

= root 6/4

= root 3/2

= cos 30
