now, to get the y-intercept, we simply set x = 0 and solve for y, and to get the x-intercept, we set y = 0 and solve for x.
Answer: (b) 48 cm
==========================================================
Explanation:
Divide the perimeter of the square over 4 to get the side length s.
s = P/4
s = 48/4
s = 12
The side length of the square is 12 cm. This leads to an area of...
A = s^2
A = 12^2
A = 144
The area of the square is 144 square cm.
The rectangle is 4 cm^2 less than the square's area, so we know the rectangle has area 144-4 = 140 cm^2.
If the length of the rectangle is 14 cm, then the width must be
W = A/L
W = 140/14
W = 10
This is a 14 cm by 10 cm rectangle (note how 14*10 = 140)
The last step is to compute the perimeter of the rectangle
P = 2(L+W)
P = 2(14+10)
P = 2*24
P = 48
You can use the formula P = 2L+2W, but it's effectively the same thing.
The perimeter of the rectangle is 48 cm.
The most likely thing that has happened in this case is that a fee is paid for the registration.
The function that best models this problem is:
y = 45x + 15
Where,
x: number of months.
Y: payment of each month.
For the first month we have:
y = 45 (1) +15
y = 45 + 15
y = 60
answer:
the most likely reason for the bill being this amount is
registration fee.
Your answer will be 5850 30% of 4500 is 1350.
4500 + 1350 = 5850.
