Write an expression for the perimeter of the triangle shown below: (4 points) A triangle is shown with side lengths labeled 0.5x plus 9, 3x, and negative 3.4x minus 25.

A 6.9x − 16

B 6.9x + 16

C 0.1x − 16

D 0.1x + 16

The expression of the perimeter of the triangle is 0.1x - 16 ⇒ C

Step-by-step explanation:

The perimeter of a triangle is the sum of the lengths of its sides

Let us solve the problem

∵ The lengths of the sides of a triangle are:

∵ The perimeter of the triangle = sum of lengths of its sides

∴ The perimeter = (0.5x + 9) + (3x) + (-3.4x - 25)

→ Add the like terms

∵ The perimeter = (0.5x + 3x - 3.4x) + (9 + -25)

→ Remember (+)(-) = (-)

∴ The perimeter = (3.5x - 3.4x) + (9 - 25)

∴ The perimeter = 0.1x + -16

∴ The perimeter = 0.1x - 16

The expression of the perimeter of the triangle is 0.1x - 16

its 4 because 2 times 2 is 4, if you double the number two you get four
