Find the value of x.<br><br> A.<br> 7<br> B.<br> 9<br> C.<br> 11<br> D.<br> 12
Arisa [49]
Use the law of cosines to solve for angle A. Plug your known side length values into the equation a^2 = b^2 + c^2 – 2bc cos A.

Then use the law of sines to find angle B. (Sin A/a = Sin B/b = Sin C/c).

Because the two red angles within B are congruent, divide your angle measure in half.

From there, do the law of sines to solve for x. Good luck!

For what value of p the equation [p-3]x²+4[p-3]+4=0
Vikentia [17]

Step-by-step explanation:

(p-3)[x²+4]+4=0

(p-3)[x²+4]=-4

(p-3)=-4/x²+4

p=-4/x²+4+3

p=-4+3(x²+4)/x²+4

p= -4+3x²+12/x²+4

p=8+3x²/x²+4

Select the correct answer.
Tanya [424]

Answer:

The function f has an inverse because it is one-to-one.

Step-by-step explanation:

The condition for a function to have an inverse is that every x coordinate maps to a single y - coordinate. As illustrated by the diagram attached in the second picture, every x value maps to one y value therefore satisfying the condition making the function have an inverse.

Just tell me the answer and how you got it , thank you​

(2x^2 + 4x + 6) - (-3x - 5x^2 + 4)

The negative sign separating the expressions is just multiplying the rightmost expression by -1.

(2x^2 + 4x + 6) + (3x + 5x^2 - 4)

Now, let's add together terms that share the same variable.

2x^2 + 5x^2 = 7x^2

4x + 3x = 7x

6 + (-4) = 2

Let's combine each of these terms into one expression.

7x^2 + 7x + 2 is the final answer.
