A hole occurs when both numerator and denominator of a rational function have the same factor.
<u>Step-by-step explanation:</u>
While graphing rational function, it has to be converted into the lowest terms by factoring the numerator and denominator. If the numerator and denominator has the same factor, a hole is said to have occurred and to solve the rational function, you have to set the common factor to zero.
After you set it to zero and solve, you obtain the x value which can be then used to find out the value of y.
Answer:

Option C)
Step-by-step explanation:
Here we are given with the expression 
The GCF of
and 12 is 3
Hence we take 3 as GCF and bring it in front of the bracket.

It can not be factorise furthure as there is no GCF of 25 and also there is no rule for sum of squares so that we may apply it on this. Hence the answer would be

Option C)
Answer:
300
Step-by-step explanation:
10 x 30= 300
To find the area of a semicircle you would use the formula A=pie * r ^ 2 If you fill in 40 for r you would get 5026.5482
