Answer:
x=7+√15
x=7-√15
Step-by-step explanation:
A :-) 4 ( x - 7 )^2 - 48 = 12
= 4 ( x^2 - 49 ) - 48 = 12
= 4x^2 - 196 - 48 = 12
= 4x^2 - 244 = 12
= 4x^2 = 12 + 244
= 4x^2 = 256
= x^2 = 256 by 4
= x^2 = 64
= x = _/64
= x = 8
.:. x = 8

1c. Yes
Step-by-step explanation:
The kinetic energy transfers from the moving ball to the non-moving ball.
Sinα=h/L where h=height, L=string length...
h=Lsinα so
h(25°)=50sin25≈21.1ft
h(45°)=50sin45≈35.4ft
