Answer:

What is missing is -5x - 20

Step-by-step explanation:

To find this, simply solve for the parenthesis as if it were a variable of its own. This will allow you to see exactly what is missing.

8x - (x - 20) = 2x - (_______)

8x - x + 20 = 2x - (_______)

7x + 20 = 2x - (_______)

5x + 20 = - (_______)

-5x - 20 = (_______)

So the answer for the parenthesis is -5x - 20

Mrs. McDonnell is making 25 paper cones to fill
viktelen [127]

Answer:

(A)29 cubic inch

Step-by-step explanation:

Diameter of the Cone =4 Inches

Height of the Cone =7 Inches

Volume of a Cone =\frac{1}{3}\pi r^2h

First, we determine the radius, r.

Radius=Diameter/2=4/2=2 Inches

Therefore:

Volume of one paper cone =\frac{1}{3}\pi *2^2*7

=29.32 cubic inch

=29 cubic inch (to the nearest cubic inch.)
