The answer is 14285
28357-14072=14258
Answer:
Step-by-step explanation:
The area (A) of a rectangle is equal to the length (L) of one of its sides times its width (w)
(eq. 1)
And its perimeter can be calculated with the next formula:
P=2(L+w) (eq. 2)
Solving for <em>w </em>in eq. 1, and plugging it into eq. 2
(eq. 3)
(eq. 4)
We know that A=49m^2, plugging in this value into eq. 4, we finally get into the answer:
If the length of the rectangle is larger than its width:
We know that a length can't be negative value, so the only valid interval is L>7. The domine of P is then:
L>7
Multiplying through by 8 we get
2x + 8 = 3x
8 = 3x - 2x
x = 8 (answer)
128000 x .2= 25,600
Your down payment 25,600.
1/x is smallest when x is the largest it can be, so it is 1/3
1/y is smallest when y is the largest it can be, so it is 1/5
The average of 1/3 is 1/5 can be found by adding them together and dividing by 2:
1/3 + 1/5 = 5/15 + 3/15 = 8/15
Divide it by 2:
4/15
The answer is C.
