A triangle has side lengths of (8h - 9) centimeters, (4h + 5) centimeters, and (9k – 5) centimeters. Which expression represents the perimeter, in centimeters, of
the triangle?

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.

is there a question here?

step-by-step explanation:

sina-sinb

cosb+cosa

tana-tanb

cos0+cos x pi/3

20tan

step-by-step explanation:

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
