Sosceles triangle PQR is shown in the diagram. Isosceles triangle PQR is shown in the diagram.

Which statement about the medians of △PQR is true?
A)The medians of △PQR are concurrent at a point and the medians of the congruent sides of △PQR are congruent.
B)Each median of △PQR bisects each of the other medians and creates bisected angles at the vertices of △PQR.
C)The medians of △PQR connect to create four congruent isosceles triangles in the interior of △PQR.
D)The medians of △PQR are perpendicular to the side opposite the vertex, creating two congruent triangles.

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!

step-by-step explanation:

3x^3-2x^2+4x-3= -3

x^2+3x+3= 3

-3÷3= -1

the cost of 6 show tickets is $30.

step-by-step explanation:

look closely at the graph, where it says 6 that's the amount of tickets. go up until you reach the dot. the dot shows that the coordinates are (6, 30). there fore from that you can infer that 6 show tickets cost $30.
