Analyze relationships The area of the shaded triangle is 5x2 3x 4 What is the area of the entire figure class=

Respuesta :

well, we know the shaded region has an area of 5x²+3x-4, there are three more sections of equal shape, so their areas must also be equal, meaning there are four regions of the same area of 5x²+3x-4, thus 4(5x²+3x-4) = 20x²+12x-16.
