The answer is b because 90 plus 50 equals 140. and the sum of all the angles i a triangle is 180. So you subtract 140 from 180 and get 40.

Identify whether each value of x is a discontinuity of the function by typing asymptote, hole, or neither. 5x/ x3 + 5x2 + 6x
tatiyna

Answer: hole at x = 0, asymptotes at x = -2 and x = -3

<u>Step-by-step explanation:</u>

  \frac{5x}{x^{3} + 5x^{2} + 6x}

= \frac{5x}{x(x^{2}+5x + 6)}

= \frac{5x}{x(x+2)(x+3)}

x ≠ 0 ---> the x cancels out so this is a hole  

x + 2 ≠ 0   ---> x ≠ -2   ---> asymptote at x = -2

x + 3 ≠ 0   ---> x ≠ -3   ---> asymptote at x = -3

FOR 100 POINTS!!!!!!!!!!!<br><br>Solve the equation. <br><br><br>3(4x + 4) = 2(5x + 9) - 12
Tatiana [17]

Answer:

<h3>X=-3</h3>

Step-by-step explanation:

Isolate x on one side of the equation.

<u><em>DISTRIBUTIVE PROPERTY</em></u>

A(B+C)=AB+AC

A(B-C)=AB-AC

3(4x+4) (First, expand.)

3*4x=12x

3*4=12

12x+12

2(5x+9)-12

2*5x=10x

2*9=18

10x+18

18-12=6

12x+12=10x+6

12x+12-12=10x+6-12 (Subtract 12 from both sides.)

6-12 (Solve.)

12-6=6

12x=10x-6

12x-10x=10x-6-10x (Subtract 10x from both sides.)

12x-10x (Solve.)

12x-10x=2x

2x=-6

2x/2=-6/2 (Then, divide by 2 from both sides.)

-6/2 (Solve.)

-6/2=-3

x=-3

As a result, the final answer is x=-3.

Since the ratios for sides of triangles are the same, when the angles are the same, ? have been developed which show these ratio
Scilla [17]
Presuming that I am reading the question correctly, the answer is D. A trigonometric table would provide all of the ratios of the sides in relationship to the angles. Sin, cos, and tan are just one example of the ratio.
