Answer:
The area of the lawn is 68
.
Step-by-step explanation:
Area of lawn = Area of garden - (Area of triangle + Area of trapezium)
Area of garden = length x width
= 14 x 10
= 140 ![m^{2}](https://tex.z-dn.net/?f=m%5E%7B2%7D)
Area of triangle =
x base x height
=
x 3 x 8
= 12 ![m^{2}](https://tex.z-dn.net/?f=m%5E%7B2%7D)
Area of trapezium =
(a + b) h
=
(5 + 7) 10
= 60 ![m^{2}](https://tex.z-dn.net/?f=m%5E%7B2%7D)
So that;
Area of lawn = 140 - (12 + 60)
= 140 - 72
= 68 ![m^{2}](https://tex.z-dn.net/?f=m%5E%7B2%7D)
The area of the lawn is 68
.
Answer:
option A
![\frac{(x+2)(x+5)}{x^{3}-9x }](https://tex.z-dn.net/?f=%5Cfrac%7B%28x%2B2%29%28x%2B5%29%7D%7Bx%5E%7B3%7D-9x%20%7D)
Step-by-step explanation:
Take LCM
![\frac{2x+5}{x(x-3)}-\frac{3x+5}{x(x^{2}-9)}+\frac{x+1}{(x+3)(x-3)}](https://tex.z-dn.net/?f=%5Cfrac%7B2x%2B5%7D%7Bx%28x-3%29%7D-%5Cfrac%7B3x%2B5%7D%7Bx%28x%5E%7B2%7D-9%29%7D%2B%5Cfrac%7Bx%2B1%7D%7B%28x%2B3%29%28x-3%29%7D)
![\frac{2x+5}{x(x-3)}-\frac{3x+5}{x((x+3)(x-3))}+\frac{x+1}{(x+3)(x-3)}](https://tex.z-dn.net/?f=%5Cfrac%7B2x%2B5%7D%7Bx%28x-3%29%7D-%5Cfrac%7B3x%2B5%7D%7Bx%28%28x%2B3%29%28x-3%29%29%7D%2B%5Cfrac%7Bx%2B1%7D%7B%28x%2B3%29%28x-3%29%7D)
![\frac{(2x+5)(x+3)}{x(x+3)(x-3)}-\frac{3x+5}{x((x+3)(x-3))}+\frac{(x+1)(x)}{x(x+3)(x-3)}](https://tex.z-dn.net/?f=%5Cfrac%7B%282x%2B5%29%28x%2B3%29%7D%7Bx%28x%2B3%29%28x-3%29%7D-%5Cfrac%7B3x%2B5%7D%7Bx%28%28x%2B3%29%28x-3%29%29%7D%2B%5Cfrac%7B%28x%2B1%29%28x%29%7D%7Bx%28x%2B3%29%28x-3%29%7D)
Now the Denominator is same we can add the numerator
![\frac{(2x^{2}+11x+15)}{x(x+3)(x-3)}-\frac{3x+5}{x((x+3)(x-3))}+\frac{(x^{2}+x)}{x(x+3)(x-3)}](https://tex.z-dn.net/?f=%5Cfrac%7B%282x%5E%7B2%7D%2B11x%2B15%29%7D%7Bx%28x%2B3%29%28x-3%29%7D-%5Cfrac%7B3x%2B5%7D%7Bx%28%28x%2B3%29%28x-3%29%29%7D%2B%5Cfrac%7B%28x%5E%7B2%7D%2Bx%29%7D%7Bx%28x%2B3%29%28x-3%29%7D)
![\frac{2x^{2}-x^{2}+11x-3x-x+15-5}{x(x+3)(x-3)}](https://tex.z-dn.net/?f=%5Cfrac%7B2x%5E%7B2%7D-x%5E%7B2%7D%2B11x-3x-x%2B15-5%7D%7Bx%28x%2B3%29%28x-3%29%7D)
![\frac{x^{2}+7x+10}{x(x+3)(x-3)}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7B2%7D%2B7x%2B10%7D%7Bx%28x%2B3%29%28x-3%29%7D)
![\frac{(x+2)(x+5)}{x(x+3)(x-3)}](https://tex.z-dn.net/?f=%5Cfrac%7B%28x%2B2%29%28x%2B5%29%7D%7Bx%28x%2B3%29%28x-3%29%7D)
![\frac{(x+2)(x+5)}{x^{3}-9x}](https://tex.z-dn.net/?f=%5Cfrac%7B%28x%2B2%29%28x%2B5%29%7D%7Bx%5E%7B3%7D-9x%7D)
