a^2 + a^2 = 2 a^2
a^ 2 x a^2 = a^4
Ten yards = 30 feet
30 feet x 12 in/ft = 360 inches
360 inches / (2 inches/sec) = 180 Seconds = 3 minutes He MIGHT be 71 when he gets to the other side!
Generally, it's easiest when the leading coef is one
(z-8)(z+2)
Another way....you are dividing by a fraction, so flip the denominator and multiply
(1 + sqrt(2)) x 2/sqrt (2)= 2/ sqrt2 +1
Then simplify the first term by multiplying by sqrt2/sqrt2
sqrt2/sqrt2 (2/sqrt2) + 1 = 1 + sqrt2

Torque is the twisting force that tends to cause rotation. The point where the object rotates is known as the axis of rotation. Mathematically torque can be written as T = F * r * sin(theta), and it has units of Newton-meters. When the sum of all torques acting on an object equals zero, it is in rotational equilibrium.
