Chrissy's score = c
Twice means multiply by 2
twice Chrissy score = 2c
the sum of 22 and twice Chrissy score: 22+2c
Answer:
thanks
Step-by-step explanation:
Area of a rectangle = b*h... so 6ft*5ft = 30 ft^2
The highlighted sector is exactly 3/4 of the circle area, because is 3/4 of which is a complete rotation.
Since you are given the radius, you can compute the area as
So, 3/4 of this area would be squared cm.
The remaining sector, of course, is squared cm.
Answer:
Step-by-step explanation:
We want to factor the expression .
First, notice that this is in quadratic form. In other words, both the exponents have even power.
Therefore, we can make a substitution to simplify the expression.
So, let’s let .
Our expression is the same as:
Substitute:
Now, we can factor like normal. We can use -1 and -4. Therefore:
We can now substitute back u:
Both of these can be factored furthered using the difference of two squares:
Therefore, we will have:
And we are done!
