You want to make sure to factor each equation as much as you can first.
So just focus on the numerator first.
To factor the numerator:
factor out an x
factor out the rest completely.
Now for the denominator:
factor out a -4
factor out the rest.
This leaves you with:
Then you can simplify:
I'm not sure what you're supposed to find exactly, so if you need more help you can ask me (:
Answer:
The width of the rectangle is 2.5 feet
Step-by-step explanation:
Here, we want to calculate the width of the rectangle given its length
Let the area = perimeter = x
Mathematically;
area of rectangle = L * B = 10B
The perimeter of the rectangle = 2(L + B)
Also;
x = 10B
Let’s equate this to the perimeter
x = 10B = 2(L + B)
10B = 2(10 + B)
10B = 20 + 2B
10B -2B = 20
8B = 20
B = 20/8
B = 5/2
B = 2.5
Answer:
Step-by-step explanation:
All the reasons are correct apart from the 4th.
Step 4 involves <u>multiplication</u> of both sides by (2/3). Thee reason given is: "<u>Division</u> property of equality", which is wrong as division is not applicable.
Use the compound interest formula.
A = P*(1 +r/n)^(n*t)
where P is the principal, r is the annual rate, n is the number of compoundings per year, and t is the number of years.
For the first investment, ...
A = 208,000*(1 +.08/4)^(4*5) = 309,077.06
For the second investment, ...
A = 218,000*(1 +.07/2)^(2*4) = 287,064.37
Totaling both investments at maturity, Megan has $596,141.43.
