Consider the diagram below of an equilatera triangle.

4 = n.

13 ft.

Step-by-step explanation:

An equilateral triangle means that all of the sides are equal.

This means: 2n + 5 = 3n + 1 = 5n -7

You can pick two of those sides to set up an equation to solve for n.

For example, 2n + 5 = 3n + 1.

Then you will need to isolate the variable.

Subtract 1 from each side to get 2n + 4 = 3n.

Subtract 2n from each side to get 4 = n.

Substitue 4 for n into one of the equations.

2n + 5

2(4) + 5

8 + 5 = 13

Each side is 13 ft.

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this

236 cm 16 time 12 = 192

6 times 7 = 42

192+42
