330/3= 110
550/110=5
Answer is 5 books
A. Similar triangles have equal angles even though they're not the same size that was similar means So then
X^2-5x=4x+36
X^2-5x-4x-36=0
X^2-9x-36=0
(X-12)(x(+3)
X=12. X=3
Angle C and angle F are equal
So 4(12)-5=43
Rewrite in standard form using (h,k) to find the vertex.
(3,4) is the answer.
The answer to this question would be 3d-2=31 and d=11
