Q5.To what expression must 99x3-33x2-13x-41 be added to make the sum zero?​

Answer 1

Answer:

377:1498  

Step-by-step explanation:

Area of covered land by plants =9×1=9m  

Area of rectangular land =15×10=150m  

Area of covered land by camel =5×3=15m    

Region of land covered by ox in circular area with diameter, d=2.8m  

⇒Radius =1.4m

Region of land covered by ox  

=πr = 22 /7  ×1.4×1.4=6.16m

Total area covered by Camels, plants and ox =9+15+6.16=30.16m  

Therefore, remaining land =150−30.16=119.84m  

Ratio of areas kept for animals and plants to the living areas 30.16:119.84=754:2996=377:1498
