Answer: 44 boys and 40 girls
Step-by-step explanation:
x = number of girls
x + 4 = number of boys
x + x + 4 = 84
2x + 4 = 84
2x = 80
x = 40
84 - 40 = 44
(a) The sum of length and width is half the perimeter, so the breadth in terms of length (x) in cm will be
.. breadth = 34 -x
(b) Then the expression for the area (in cm^2) is
.. area = length*breadth
.. 253 = (x)(34 -x)
.. x^2 -34x +253 = 0 . . . . . subtract the right side, eliminate parentheses
.. (x -11)(x -23) = 0 . . . . . . . factor
.. x = 11 or 23
The dimensions of the rectangle are 11 cm by 23 cm.

You really just need the little table they provide to figure this one out, but here we go!
<span>First, you must find what class the person falls under. For this, it would be Class 3 since it is used for business purposes, but no male under 25 has driven it. You then find the premium for 100/300 under class 3, which is $549.70 and the property damage of 25,000 (The 25 in 100/300/25 means the damage in thousands), which is $98.20 and add the two together. So the total premium would be $647.90 in total annual premium.</span>
I believe the answer is 5.73
