Answer:
The first question is A.
The second question is C.
The thid question is B., I think i'm not quit sure sorry
F(x) = x^2 +5x + 3
= (x + 2.5)^2 - 6.25 + 3
= (x + 2.5)^2 - 3.25
That is vertex form. I am not sure what you mean by function form
Answer:
8) scale factor: 3
angles Q & L, S & N, r & M
sides 10 x 3 = 30, 6 x 3 = 18, 13 x 3 = 39
9) scale factor: 0.4
angles B & F, C & G, D & H, A & E
sides 9 x 0.4 = 3.6, 7.5 x 0.4 = 3, 10 x 0.4 = 4, 12 x 0.4 = 4.8
False, An example would be an equilateral triangle with 3 sides of 3 inches, and another with three sides of 5 inches. They will be similar but not congruent because their sides differ. because the sides and volumes differ they will not be congruent.
