Answer:
11.33 * 16.33 meters to the nearest hundredth.
Step-by-step explanation:
Let the width of the pool be x meters, then the length is x+5 meters.
The length of whole area = x + 5 + 2(3) = x + 11 meters and the width is
x + 2(3) = x + 6 meters.
So we have the equation (x + 6)(x + 11) = 387.
x^2 + 17x + 66 = 387
x^2 + 17x - 321 = 0
x = [-17 +/- sqrt (17^2 - 4*1*-321)] / 2
x = 11.33 meters
So the width is 11.3 m and the length is 16.33 meters.
I believe one answer could be (4x4)=16-10=6+12=18+10=28-4=24?
Answer:
Step-by-step explanation:
total price was reduced by $ 7
let x = the total price........ x - 7
he bought 10.....and it cost him $ 130
10(x - 7) = 130
10x - 70 = 130
10x = 130 + 70
10x = 200
x = 200/10
x = 20 <====== original price
Answer:
For my answer what I got was -118
If its wrong im sorry but I hope this helps :3
Answer:
Step 1 :
Split the figure into 3 parts
part 1: triangle with base = 7 + 2 + 6 = 15in, height = 7in
part 2 : Rectangle with breadth = 3 + 6 + 2= 11in and length 8in
Part 3 :Rectangle with breadth 2in and length 9in
Step 2 :
find the area of each part
Area of part 1
Area of part 2
Area of part 3
Total area = 52.5 + 88 + 18 = 158.5 sqaure inches
