Which of the following uses the distributive property correctly?
34x + 5) = 3 · x-3.5
3(x + 5) = 3 . x+5
3(x + 5) = 3 • x+3.5
3(x+5) = 3 + 3.5

3(×+5)=3 . x+5

Step-by-step explanation:

3(x+5)=3x+15

3 . x+5=3x+15

3 (x+5)=3 . x+5

the correct answer is option c.   3

step-by-step explanation:

points to remember

equation of the line with coordinates (x₁, y₁) and (x₂, y₂) is given by,

slope m = (y₂ - y₁)/(x₂ - x₁)

from the figure we can see a line with two coordinates given

to find the slope of given line

here   (x₁, y₁)   = (-1, -1 ) and (x₂, y₂) = (1, 5)

slope m = (y₂ - y₁)/(x₂ - x₁)

  = (5 - -1)/(1 - -1)

  = (5 + 1)/(1 + 1)

  = 6/2 = 3

therefore the correct answer is option c.   3
