5. the sum of the perimeters of two different equilateral |
triangles is 45 centimeters and the difference between their
perimeters is 15 centimeters. let x equal the side length of
the larger triangle and let a equal the side length of the
smaller triangle. write a system of linear equations that can
be used to find the dimensions of the large and small triangle.

answer: $1794

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

the answer would be a 24

step-by-step explanation:

c=2πr=2·π·3=24
