A right triangle has a perimeter of 31 centimeters. The lengths of the sides of the triangle are each multiplied by 5 to make a new triangle. What is the perimeter of the new triangle?

155 cm

Step-by-step explanation:

so just pretend the old lengths of the triangle were 9,10,12

then multiply them by 5

so the lengths are 45,50,60

therefore the new perimeter is 155 cm

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
