Answer:
Step-by-step explanation:
The dimensions of the pool is 15m by10m
<h3>Area and perimeter of rectangle</h3>
A pool is rectangular in nature. If a rectangular swimming pool has an area of 150 square meters and a perimeter of 50 meters, then;
lw = 150
2(l+w) = 50
l + w = 25
where
l is the length
w is the width
From the equation 3
l = 25 - w
Substitute into 1
(25-w)w = 150
25w-w² = 150
w²-25w+150 = 0
w²-10w-15w+150 = 0
Factor
w(w-10)-15(w-10) = 0
w = 10 and 15
l = 150/10 = 15
Hence the dimensions of the pool is 15m by10m

Y = -2x + 5
All you have to do when coming across this type of problem is substitute x and y for the points given, as well as change whatever b is, in this case 5, for b. For example: -3 = -2(4) + b
You would do 375 divided by 60% and get 6.25 if need to round to nearest whole it would be 6
