1) Which expression represents the perimeter of the triangle drawn below?

The triangle has (x-1) on the left side.
(x+2) is on the bottom of the triangle.
(2x-4) is on the slanted top.

A) 3x-3
B) 3x-5
C) 4x-3
D) 4x-5

I do not know how to do this, so help would mean so much to me. Thank you!

Never mind, I think I got it! Is it C?

Yes, I think the answer is C Sasha.

To find the perimeter of the triangle, we need to add up the lengths of all three sides.

The left side of the triangle is given as (x-1).
The bottom of the triangle is given as (x+2).
The slanted top of the triangle is given as (2x-4).

To find the perimeter, we add up the three sides:

Perimeter = (x-1) + (x+2) + (2x-4)

Now, let's simplify the expression:

Perimeter = x - 1 + x + 2 + 2x - 4

Combine like terms:

Perimeter = 4x - 3

So, the expression that represents the perimeter of the triangle is 4x - 3.

Therefore, the correct answer is option C) 4x - 3.

To find the perimeter of a triangle, we add up the lengths of all three sides. In this case, the left side has a length of (x-1), the bottom has a length of (x+2), and the slanted top has a length of (2x-4).

Perimeter = (x-1) + (x+2) + (2x-4)

Next, let's simplify the expression by combining like terms:

Perimeter = x - 1 + x + 2 + 2x - 4

Now we can combine the x terms and the constant terms:

Perimeter = (x + x + 2x) + (-1 + 2 - 4)

Perimeter = 4x - 3

So, the expression that represents the perimeter of the triangle is 4x - 3.

Therefore, the correct answer is option C) 4x-3.
