Does the choice of the base affect the perimeter of a triangle?

No.
The perimeter is the distance all the way around the triangle.
So it's the sum of the lengths of the three sides.

The sum of three numbers doesn't depend on what order you
add them ... I think that's the 'commutative' property of addition.

So it doesn't matter which side you start with, or even what order
the sides are arranged in. The perimeter is always the same.

Answer:

x=14/5

Step-by-step explanation:

Group like terms

2x+8x+7=35

Add similar elements: 2x+8x=10x

10x+7=35

Subtract 7 from both sides:

10x+7−7=35−7

Simplify

10x=28

Divide both sides by 10

10x/10 =28/10

Simplify:

x=14/5

There are two green marbles out of the 10 marbles. 2/10
2 divided by 10 is .20 or 20%
