Calculate and sum up the first three terms.

We get:

4[ (1/2)^(1-1) + (1/2)^(2-1) + (1/2)^(3 - 1) ], OR

4[ 1 + (1/2) + (1/2)^2 ], or

4[1 + 1/2 + 1/4} = 4[7/4] = 7

Subtract (5 − 2i) − (1 + 8i). Which property allows you to write the expression as 5 − 2i − 1 − 8i?

GrogVix [38]

This is the concept of algebra, we are required to subtract the complex numbers. Thus;
(5-2i)-1(1+8i)
opening the brackets using the distributive property we get:
5-2i-1-8i
collecting the like terms we get:
5-1-2i-8i
=4-10i
the answer will therefore be:
4-10i

Store display volume of each cube shaped box is 125 cubic inches of the display has six layers of boxes how high is the display

Doss [256]

Answer:

30 inches

Step-by-step explanation:

We know that the formula for calculate the volume of a cube is:

∨=8³

Where "s" is the length of each side.

Since the volume of each cube-shaped box is 125 cubic inches, we can find "s":

125 in³=8³

∛125 in³=8

8=5 in

We know that the display has six layers of boxes, then , to calculate the height of the display, we can multiply the value of "s" obtained before by 6.

Then:

height= (5 in)(6)=30 in
