Answer:
This expression is missing operators and has no meaning. If you add commas to separate the expressions, and equals signs where appropriate, then assistance can be given.
Assuming that the blank spaces between terms are meant to be plus signs, then the final answer would be 9x.
Step-by-step explanation:
To make some sense of this, let's assume that the operator between "5x-4" and "6x-23" is a plus sign, and that the minus sign on "-2x + 33" is itself the operator there. If that is the case then this can be solved by simply grouping like terms and summing them up:

group like terms:


The numbers with no coefficient add up to zero:

Leaving us with the final answer.

Answer:
1/16
Step-by-step explanation:
1/2 of 1/2 is 1/4 then 1/4 of 1/4 is 1/16

Answer:

Step-by-step explanation:
The reference angle is an acute angle that angle in standard position makes with the positive x-axis.
The given angle in radians is

This angle is already acute and hence it is itself a reference angle.
The reference angle of any angle in the first quadrant is the same angle.
