Group and factor/undistribute
(x^2y^3-2y^3)+(-2x^2+4)
(y^3)(x^2-2)+(-2)(x^2-2)
see the (x^2-2) is common term so undistribute
(x^2-2)(y^2-2)
last one
Answer:
10
Step-by-step explanation:
2/5 yard = 0.4 yard each piece
4 / 0.4 = 10
Answer:
-5y-4=-(x+3)2-1/(2)
Step-by-step explanation:
(16/18)
(24/27)
You just times 8 and 9 by the same number, like:
(8•2/9•2)=(16/18)
(8•3/9•3)=(24/27)
You could do any number:
(8•100/9•100)=(800/900)
The period of oscillation of a pendulum is

Where L is the length of the pendulum and

the gravitational acceleration.
Re-arranging the formula and using T=1.0 s, we find the length of the pendulum:
