Answer:
9/20 or 0.45 as a decimal.
Step-by-step explanation:
(a^2)/b
= (3/2)^2 / 5
= 9/4 / 5
= 9/4 * 1/5
= 9/20.
Total of non home owners is 45 + 85 = 130
Percentage would be 130/250 = 0.52
0.52 x 100 = 52%
Number who have no car or one car = 20 + 45 = 65
Percentage = 65/250. = 0.26 = 26%
40% is like 40/100 which simplifies to 2/5
Answer:
3x²-11x-14=0
Step-by-step explanation:
Given equation is : (3x²+6x+7)-(6x²-5x-7)
Putting the equation equals to zero making it in the form of polynomial equation (3x²+6x+7)-(6x²-5x-7)=0
Opening the bracket of the equation, the negative sign outside the bracket changes the sign of the values after opening the bracket.
3x²+6x+7-6x²+5x+7=0
Solving this by subtracting the values of same type i.e subtracting the component of x having the same power.
3x²-6x²+6x+5x+7+7=0
-3x²+11x+14=0 OR 3x²-11x-14=0
So, on subtracting the above equation the quadratic equation is obtained 3x²-11x-14=0
I think it the square root of 69 which could also be 420 i just need the points
