what is the height of the pole ?
a. 12 ft
b. 12 square root of 3 ft
c. 18 ft
d. 18 square root of 2 ft

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!

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two

is there a graph
