Answer:
B.
Step-by-step explanation:
You will need to get rid of the parenthesis to make the problem easier for you to work with. Since there is a number in front of the parenthesis, you will need to distribute that to both numbers in the parenthesis.
For this example, you would multiply the 9 to both the x and -1, and then 8 to both 2x and 2.
Answer:
x = 2/3
Step-by-step explanation:
sin²30° + cos²30° + x.tan²60° = cot²30°
=> (1/2)² + (√3/2)² + x(√3)² = (√3)²
=> 1/4 + 3/4 + 3x = 3
=> 3x = 2
=> x = 2/3
Answer:
1
Step-by-step explanation:
Ok, so the third and fourth don't seem right. I am going to assume it's either 1 or 2. Sorry if you get it wrong because of me.

Answer:
24
Step-by-step explanation:
The product of lengths from the point where the secants meet to the near and far circle intersection points is the same for both secants.
RQ·RC = RS·RT
8(27) = (3x)(8x)
9 = x^2 . . . . . . . . . divide by 24
3 = x
Then the length of interest is ...
TR = 8x = 8·3
TR = 24
9 and 3/8 is 75/8 as a mixed #.
