Answer:
when this quadratic is equal to 0
3(3x^2+13x+14)=0
3(3x+7)(x+2)=0
3 is not equal to 0
therefore (3x+7) or(x+2)=0
So (77 5/7)/17
5/7 = 0.7142
77.7142/17
=4.5714 rupees per metre
14.
1. 7 × 7 = 49
2. 7 × 3 × 3 = 63
3. 7 × 3 × 4 = 84
4. 7 + 3 + 4 = 14
Hope that helps! Feel free to ask for a more explanation, if needed.
Given:
An unpainted roof. Assuming the dimensions of the roof are 10 meters by 5 meters by 0.2 meters. To solve for the total surface area of the roof to be painted:
SA = 2 (wl + lh + wh)
SA = 2 ( 10*5 + 10*0.2 + 5*0.2)
SA = 106 square meters
You must divide the cost in 2011 by 1955 for each item and round your answer to the nearest hundredth after.
Hope that helps!
