What is 8 +2+8+8+8+8+7+9+9+9+9+9+9+0+9+9+9090 90+9+9-9+9

909,220

Step-by-step explanation:

8x5=40

2

7

9x9=81 (two of the 9s cancel out)

909,090

Add all of the numbers from above to get 909,220. The format of this question was really weird. Either your homework was stupid or you were messing with someone when you wrote this but I hope I passed your test if you were trying to trip me up lol.

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

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
