Question 1 is either B or D
Answer:
x^2 - 6x + 147 so the coefficient is 1
Step-by-step explanation:
First, simplify the equation.
1. 2/3x(2x-3) = (2x/3)(2x-3)-(x-7)(x+7)
2. 2x-3(2x/3) = (2x(2x-3)) - (x-7)(x+7)
3. Expand -(x-7)(x+7) = -x^2+49
Combine to get (x^2 - 6x)/3 +49
Simplify to get x^2 - 6x + 147. The coefficient of the quadratic term is one.
Answer:
12.5 cm
Step-by-step explanation:
0.625km=62500cm. The scale factor is 1:5000. So the distance on the map will be 62500/5000=12.5 cm
12.5 x 2 (you need the diameter to find pi) =25pi ft
