Answer:
g(f(x)) =3(x2)+1
Step-by-step explanation:
g(f(x)) means substitute f(x) in the eqn g(x)
That is anywhere you see x2, use it to replace x in the eqn g(x)
Little tip ** if u r going from a larger shape to a smaller shape, the scale factor is going to be a proper fraction....a number less then 1 but greater then 0
BC = 66......EF = 11.......66 times what is 11
66x = 11
x = 11/66 reduces to 1/6
so 66 * 1/6 = 11
now compare the other sides...
42 * 1/6 = 7.......looks like AC and DF
72 * 1/6 = 12...looks like Ab and DE
so ur multiplying every number in the big triangle by 1/6 , and getting the measures of the little triangle....so ur scale factor is 1/6 <==
Answer:
SAS
Step-by-step explanation:
the two triangles have two congruent sides and one congruent angle
