They sold 187 small bags and 75 large bags.
Two variables L and S (large & small)
We know that L + S = 262 -> the amount of bags sold
We also know that 3L + 1S = $412 -> total money made
L = 262 - S
Plug that into the second equation:
3(262 - S) + 1S = 412
786 - 3S + 1S = 412
786 - 2S = 412
786 - 412 = 2S
374 = 2S
S = 187
187 small bass and
So they sold 187 small bags
L = 262 - 187 = 75
They sold 75 large bags.
First, find the area of the entire traingle using the formula bh/2.
18*9/2=81 cm^2
Then subtract the area of the smaller triangle within the larger one (white triangle). It has the same base but a height of only 4.
18*4/2=36 cm^2
81-36=45
Final answer: 45 cm^2
(2 - 5i) ( 2 + 5i) (i)
(4 + 10i -10i -25) (i)
(4 - 25) (i)
-21i
