B. 10 square root 5
hope this helps:)
pls mark thanks and brainliest:)
Answer:
x = 14
Step-by-step explanation:
Extend line AB so that it intersects ray CE at point G. Then angles BGC and BAD are "alternate interior angles", hence congruent.
The angle at B is exterior to triangle BCG, and is equal to the sum of the interior angles at C and G:
138 = (376 -23x) +(x^2 -8x)
Subtracting 138 and collecting terms we have ...
x^2 -31x +238 = 0
For your calculator, a=1, b=-31, c=238.

<em>Additional comment</em>
You will find that the solutions to this are x = {14, 17}. You will also find that angle BCE will have corresponding values of 54° and -15°. That is, the solution x=17 is "extraneous." It is a solution to the equation, but not to the problem.
For x=14, the marked angles are A = 84°, C = 54°.
(2) 2x
Bc you’re adding the imaginary one infront of the x.
(1) X squared + 25
Distribution
(3) 15x-30
Distribution
(1) x to the 6 power
You add the powers when they are being multiplied
(2) 2x squared + 7x + 12
Foil method
(2) 9x + 20
Adding Like terms
(4) 12x + 25
Adding and multiplying like terms
(2) 19x + 7
Multiplying then adding like terms.
I hope this helps ;)
