Given that triangle ABC has been dilated to form triangle A'B'C' and the vertices of ABC are A(5,3), B(3,7), C(1,4) and vertices of A'B'C' isA'(7.5, 4.5), B'(4.5, 10.5), C'(1.5,6)
then the scale factor for dilation will be as follows:
Taking corresponding vertices SAY A (5,3) and A'(7.5, 4.5)
the scale factor will be:
7.5/5=4.5/3=1.5
Answer: 1.5
Answer:
no they are not proportional
Step-by-step explanation:
Answer:
(8x-9)(8x+9)
Step-by-step explanation:
64x^2 - 81
Rewriting
(8x)^2 - 9^2
We recognize that this is the difference of squares
a^2 - b^2 = (a-b)(a+b)
(8x-9)(8x+9)
Answer:
Step-by-step explanation: Supplemenatry equal 180 degrees so if you know one find the other
9/243
=9/(9*9*3)
=1/(9*3)
=1/27
