Can someone please help me?!?! I need this done before 1-5-21
Travka [436]

Answer:

8=w, -8=w  (±8=w)

Step-by-step explanation:

192=3w^{2}

First, divide by 3

64=w²

now take the square roots of 64 and w² ( we're thinking about which numbers/variables will be multiplied to get 64 and w². They are 8 and w. But wait! -8 can also work, since when you square it a negative number, it will turn positive. )

8=w, -8=w

You can also write it as ±8=w

Hope this helps!

A manhole cover has a radius of 12 inches what is the diameter of the manhole cover?
kompoz [17]
The diameter of a circle is the distance across at its widest point (right through the center). The radius is the distance from any point on the circle to the center (which means it's half of the diameter. Since we know the radius of the manhole cover is 12 inches then...

diameter = 2 × r
diameter = 2 × 12
diameter = 24 inches
