10. A triangle has side lengths of (2x - 1) units, (8x-4) units, and 5x units. Which expression
represents the perimeter of the triangle?
FX15r+ 5) units
11. (x - 4x + 5x) units
G. (10x - 10) units
J. (15x - 5) units
15xt

15x - 5units

Step-by-step explanation:

Perimeter of a triangle = addition of all sides of the triangle.

A triangle is a polygon with 3 sides.

Therefore if the sides of the triangle are 2x - 1) units, (8x-4) units, and 5x units

Perimeter = 2x - 1 + 8x -4 + 5x

Collect like terms

Perimeter = 2x + 8x + 5x -1 - 4

Perimeter = 15x - 5units

the slope of the first function is -3. (3/1)

the slope of the second function is 1. (13-10/6-3).

since |-3| is greater than |1|, the function with the steepest slope is the first.

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
