Let's find the expressions for the length and width of the rectangle. The length (which we will call <em>l</em>) is 2 units less than some undefined number, thus we will use the variable <em>x</em>:
l = x - 2
The width is 4 more than this length:
w = l + 4 = (x - 2) + 4 = x + 2
Now, given that we have the length and width and are looking for the area, we need to multiply these expressions together.
One way to write this would simply be (x + 2)(x - 2). If we wanted to find a different way of writing the area, we could use FOIL to find all terms and get x^2 - 4.
Using elimination method: x = -79/4 , y = -45/8
8.275.
If you add both and divide by two you get 8.275
<u>Answer:</u>
The present value of 10,000 if interest is paid at a rate of 6.2% compounded weekly for 8 years is 6097.56
<u>Explanation:</u>
We know that compound interest is given by
Where ,
Where A = final amount (which is given to be = 10000)
P = Principal amount (which is the present amount which we have to find)
r = interest rate = 6.2 = 0.062
n = no. of times interest applied per time period = it is given that the interest is applied weekly, so in one year there are 52 weeks so n = 52
t = time period = 8 years
Substituting the given values, we get
P = 6097.5
We get, P = 6097.56 which is the present value of a sum of money
Answer:
Step-by-step explanation:
You could look it up just like me! So here's what someone else did on brainly so I don't take credit btw.
One.
To solve this, first combine like terms.
6x + 4x - 6 = 24 + 9x
10x - 6 = 24 + 9x
Then move all like terms to one side.
10x - 9x = 24 + 6
x = 30
