Answer:

x = 18.7

Step-by-step explanation:

Gerald's answer is almost correct.

He just needs to switch the 14 and the x.

it should be

24/x = 18/14

solve for x by cross multiplication

18x = (24)(14)

18x = 336

x = 18.7

If A = {x | x is an even integer}, B = {5, 6, 7, 8}, list the elements of the set A U B

ahrayia [7]

First of all, what is an integer?

Integers are numbers such as -7, -4, 0, 5, 16... etc...

This means that even integers are numbers such as:

-4, -2, 0, 2, 4, 6, 8, 10... etc...

Which means that:

AUB={..., -4, -2, 0, 2, 4, 5, 6, 7, 8, 10, 12, 14, ...}

This is because:

The union "<span>U</span>" of two sets must contain all the numbers from both sets, providing they aren't duplicated.

<h2>Answer:</h2>

Part a. A square

Part b. A square

<h2>Step-by-step explanation:</h2>

A cube is a box that has six identical square faces. Hence if you take the cross-section by cutting the cube horizontally, that is, cutting it parallel to the base, the result is a square. Moreover, if you cut the cube vertically, cutting it parallel to the lateral face, the result is also a square. Finally, in both cases the cross-section is as shown in the figure below.
