Answer:
The equation is
n = PRT/100
The value of p
p = $1250
Step-by-step explanation:
Simple interest= n
Rate of interest = r
Number of years = t
Then principal amount= p
This p can be said to be the constant of the equation because it's value never changes
n = $225
r = 4.5%
t = 4 years
The interest varies jointly with the rate, the time and the principal amount.
The equation for the relationship
n > prt
But r is in percentage
n = PRT/100
For the value of p
p =(225*100)/(4.5 *4)
p= 22500/18
p= 1250
p = $1250
Step-by-step explanation:
By definition, the area of a rectangle is given by:
A = w * lA=w∗l
Where,
w: width of the rectangle
l: length of the rectangle
We then have the following expression for the area:
A = k ^ 2 + 19k + 60A=k
2
+19k+60
What we must do is factorize the expression following the following steps:
1) Find two numbers that are equal to 19
2) Find two multiplied numbers equal to 60
We have then:
A = (k + 15) (k + 4)A=(k+15)(k+4)
Therefore, the width of the rectangle is:
w = (k + 4)w=(k+4)
