'Undefined' typically means division by zero ... what some people would
look at and call it "infinity".

Any fraction is undefined when its denominator is zero.

2x - 1 = 0

Add 1 to each side:

2x = 1

Divide each side by 2 :

<u>x = 1/2 .</u>

The volume of a solid right pyramid with a square base is V units3 and the length of the base edge is y units.
Evgen [1.6K]

Answer:

Height of the pyramid = 3v/y² units

Step-by-step explanation:

We are given;

- The volume of a solid right pyramid with a square base = v units³

- The length of the base edge = y units

The formula for volume of a pyramid is given as;

V = ⅓ x base area x height.

Since the base is square, we will use the formula for square area which is A = side × side.

Thus, v = ⅓ × (y × y) × height

Making height the subject, we have;

Height = 3v/y²

height of the pyramid would be given by the expression 3v/y² units

I need the steps to this problem, please!

Hello Ashley!

This is an isosceles triangle. How do we know? Well, the two little bar they put means that it is isosceles. When you add all the angles together, you MUST find them equal to 180. Another you need to keep in mind is that the angle that are face to face with each other are ALWAYS equal.

Too much talking...we gonna solve the problem.

x + x + 72 = 180
2x + 72 = 180
2x = 180 - 72
2x = 108
x = 108/2
x= 54
That's the answer .

---------------------
What did we say earlier? We said that when we add all the angles together we MUST find them equal to 180. So, we gonna replace x by 54

54 + 54 + 72  = 180
180 = 180
So.. yes we got it right!

54 is the correct answer.

Good luck with your studies!
