slope = rise over run = y/x
A (-1,3) slope = 3/-1 = -3
B (1,2) slope = 2/1 = 2
C (-3,-1) slope = -1/-3 = 1/3
2 lines need to be negative reciprocals in order to be a right triangle
negative reciprocal of -3 is 1/3
so this is a right triangle
The answer is 8/3 but if your simplifying then the answer is 2 2/3 and if you want it in decimal form then the answer is 2.6 :)
one of those questions are polynomials and the one that is a polynomial is obviously the answer and that would be the third one
The answer is the second option.
We have that
<span>a triangle’s original dimensions are 24 cm by 40 cm
scale factor=2.2
then
</span>a triangle’s enlargement dimensions=[scale factor]*original dimensions
a triangle’s enlargement dimensions=[2.2]*24------> 52.8 cm
a triangle’s enlargement dimensions=[2.2]*40------> 80 cm
the answer is
a triangle’s enlargement dimensions will be 52.8 cm by 80 cm
