Solve the equation using square roots x2-14=-10

 The required solution is   x = -2,  2.

Step-by-step explanation:  We are given to solve the following quadratic equation by square root method :

In square root method, we take the square of the unknown variable on one side and the constant term on the other side. Then, we take the square roots on both sides.

From equation (i), we have

Thus, the required solution is   x = -2,  2.

439400

step-by-step explanation:

130^2 = 16900

16900*26 = 439400

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
