You can think of this equation as

and thus apply the transformations to it as such



1) D = 2, C = +3
2) D = -12, C = -2
3) C = +6, D = 3
4) C = -7, D = -7
Answer:

Step-by-step explanation:
Given

Consider the numerator:

Consider the denominator:

Hence, the fraction becomes

Consider the expression in brackets:

Divide:

Probably the property of subtraction.

Answer:
44 degrees
Step-by-step explanation:
Since MN is a tangent, it forms a right angle wheng it intersects line MP since MP is the diameter. So, 90+46 is 136 and since there are 180 degrees in a traingle, 180-136 is 44.
Hope this is helpful! :)
If you are asking which ratio is equivalent to 8 then it is neither. They are both simplified to 3:1. 54/18= 3, 18/6= 3. If you were asking if they were equivalent to each other the answer is yes.
