Answer:
For this case, we have the following equation (according to the comments):
First, we factor the quadratic expression in the denominator:
Then, we multiply both sides of the equation by (a-2) (a + 2):
Later, canceling similar terms we have:
We do distributive property on the left side of the equation:
By grouping variables and constant terms we have:
Rewriting we have:
Finally, by clearing "a" we have:
Note: the value of a is a extraneous solution because it makes the denominator of the original equation equal to zero.
Answer:
the student correct, but the value of a= -2 is an extraneous solution

Answer:
D
Step-by-step explanation:
We require to calculate the circumference (C) of the pizza
C = 2πr ( r is the radius )
here r = 10, then
C = 2π × 10 = 20π
Now divide the circumference by 4, for number of pieces, that is
number of pieces = = 5π ≈ 15.7073...
Thus 15 full pieces can be cut from the pizza
Answer:
20.9-26.2 = -5.3 to the left (or 5.3 to the right)
