Answer:
Step-by-step explanation:
The formula that is used to calculate the area of a rectangle is:
Where "l" is the lenght and "w" is the width.
You know that the area of that rectangle is:
And, according to the exercise, its lenght is 7 more than its width; then:
Then, you can make the corresponding substitution into the formula :
Simplify:
Factor the equation. Find two numbers whose sum is 7 and whose product is -744. These are 31 and -24.
Then, you get:
The width of the rectangle is the positive value:
Then, the lenght is:
The complete question is:
Henry knows that the circumference of a circle is 18π inches. What is the area of the circle?
Solution:
Circumference (C) of the circle can be written as:
Using this value of radius, we can find the Area(A) of the circle.
Therefore, area of the circle having a circumference of 18π inches will be 81π inches²

Answer:
<h3>The eventStep-by-step explanation:
Given that A denotes some event .
And also given that P(A)=0.999
<h3>To find the value ofHere the event denotes the complement of event A Therefore
contains all the events that does not occur in A.
We know that the total probability is 1
So we have that
Hence the complement of event A is
The result after combining like terms is:
Step-by-step explanation:
Given expression is:
The like terms are those terms with whom the variable or product of variables is same.
As in the given expression, first and third, both terms have x^2y so both terms are like terms
Combining like terms, means the indicated operation is performed on them
So,
Combining like terms:
Hence,
The result after combining like terms is:
