First we would find the area of the entire thing,
A=1/2(base)(height)
so A = 1/2(5)(12) = 30 mm^2
next we find the area of the smaller triangle,
A = 1/2(4)(3) = 6 mm^2
Then we subtract the area of the smaller triangle from the area of the larger one
30-6 = 24 mm^2
It would cost $38.40 because if you do $1.60 times 24 you get 38.4
Answer:
When raising an expression of that format to any power, after grouping like terms, you'll always find that the odd numbered terms are positive, and the even numbered terms are negative.
For example:
(x - y)² = x² − 2xy + y²
(x - y)³ = x³ − 3x²y + 3xy² − y³
(x - y)⁴ =x⁴ − 4x³y + 6x²y² − 4xy³ + y⁴
etc.
It is equivalent because of the distributive property. If you multiply 4 by x and y, you get 4x and 4y.
4x + 4y = 4x + 4y
