Since B and C are congruent, that means that 4x+10=x+34. Using the addition property of equality, I challenge you to solve for x! After you do that, you can note that all the angles in a triangle add up to 180, so 4x+10+x+34+angleA=180. When you find x, you can substitute that in.
If you need help with the addition property of equality for variables, here's an example - 5x+23=4x+3. Subtracting 3 from both sides, we get 5x+20=4x. Next, we can subtract 5x from both sides to get -x=20 and divide both sides by -1 to get x=-20.
Good luck, and feel free to ask with any questions!
Answer:
-8/3
Step-by-step explanation:
To solve for x-intercept, we set y as 0.
0 = 3x + 8
-8 = 3x
-8/3 = x
The x-intercept of the line is -8/3.

Answer:
The answer is D
Step-by-step explanation:
First off, the opposite of +3 is -30
Next, the opposite of 15c-30 is

Since the 2 and x^1/4 are multiplying we can do the math separately and then just multiply them afterwards
2^-4 is the same as 1/(2^4) which is 1/16
(x^1/4)^-4 (POWER RULES REVIEW)
2 exponents of same base you just add (basically multiply the two)
so x^(1/4x-4) = x^(-1)
which is just 1/x
so the answer is 1/16x
