I think it is x= 150. You add 90 plus 60. (You get 90 by the right angle) And it equals 150! I think..
f(a + 2) for f(x) = (3 + x) / (x - 3)
Substitute a + 2 for x in our equation
f(a + 2) = (3 + (a + 2)) / ((a + 2) - 3)
Combine like terms
f(a + 2) = (5 + a) / (a - 1).
This is as far as you can go.
C is the correct answer choice
Answer:
Step-by-step explanation:
for missing angle of triangle ABC
let the missing angle be y
31+111+x=180(sum of interior angle of a triangle is 180 degree)
142+y=180
y=180-142
y=38 degree
x=y(being alternate angles)
x=38 degree

;; to find the answer, set the expressions equal to each other, since the sum of the numbers should be the same.
Use

and solve for

, which would result in

.
You can also use

to find

– or

.
Plug in the values for

and

, and find

using

or

and results in

.
After plugging in the

value, you can easily find

and

.

– since 66 is the sum of a full row, and the sums of the numbers in each row, column, and diagonal are the same, so therefore,

should also equal 66. This results in

, and, using the same value for the sum of

, or

, we find that

.
The final answer is

,

Sorry it took so long;; I hope this helps :)
Combine terms using exponent rules:

First rewrite everything so that you have 2^m terms and x^m terms
