Whats the answer for -3(w+4)=-18 find what W equals
neonofarm [45]
First, distribute to simplify the equation.

-3*w = -3w
-3*4 = -12

-3w + (-12) = -18

Now, isolate the variable.
  
-3w + -12 = -18
          +12     +12

- 18 + 12 --> -6

-3w = -6

-3w/-3 = -6/-3    >>>>>     w = 2

Answer: w = 2

The lengths of the legs of a right triangle are 4 cm and 6 cm. If the triangle is rotated about one of its legs to create a righ
Assoli18 [71]
If you rotate about the leg of length 4 then the radius of the base of the cone is 6 and the height is 4.
Volume of a cone is V=1/3*pi*r^2*h
V=1/3*pi*6^2*4
=1/3*pi*36*4
=pi*48
=150.8 cm^3

To make sure that is the greatest volume we can figure the other cone.
If you rotate around the leg of length 6 your radius will be 4 and your height will be 6.
V=1/3*pi*4^2*6
V=100.5 cm^3
