Mark's score could be 120,000. Each ball would be worth 20,000 points and since 2,000 times 6 is 120,000, that's how many points he could have.
I hope this helps you
x^2+2x+8=0
x^2+2x+1+7=0
(x+1)^2= -7
(x+1)^2= i^2.7
x+1= i.square root of 7
x=-1+ i.square root of 7
A^2 - b^2 = (a-b)(a+b)
To test it, expand the right hand side.
Hello,
Yes since (2*6.4)²+9.6²=256=16²
Angle A=90°
