Answer:
Hi, There!
Option B 125% Is the Most Accurate Answer
Step-by-step explanation:
Circumference is the distance around a plane shape. So, it also measures length.
Length and area of two similar shapes are related by the formula
Where the A in both cases represents area and the L represents length. But here the Ls will represent circumference.
Since the circumference of the circle increased by 50%, then the new circumference becomes
Now subtracting from the original area then
This means that the area was increased by 1.25, which means 125%
Hence option B is the correct answer
Answer:
4 1/2 cup servings
Step-by-step explanation:
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
The phrase between 7.2 and 7.6 inclusive means:
7.2 ≤ x ≤ 7.6
