True. SAS or ASA. It shows that AD and BD are congruent and the triangles also share two sides and two angles.
Total number of marbles = 88
Number of red marbles = 25% x 88 = 0.25 x 88 = 22
Answer: There are 22 red marbles in the tin.

The formula to find the area of a circle is:

We already know this answer, so we write it as:

We need to calculate the radius (r) from this so divide both sides by 

Square root this to get r
r = 3.949327085
The formula for circumference is 
(d is the diameter )
Double the radius to get the diameter:
d = 7.89865417
Multiply this value by
to get the answer
The circumference is 24.81435391
Hope This Helps You!
Good Luck :)

The first thing to is factor the denominator of the rational function:

to do this we'll need to find two number whose product is -3 and its sum is -2; those numbers are 1 and -3, so:

Now we can rewrite our rational function as follows:

Notice that we have a common factor (x-3) in both numerator and denominator; therefore we can cancel them:

Taking all the above into consideration we realize that x=3 is a removable discontinuity; the correct answer is the first one: there is a hole in x=3 and asymptote at x=-1.
