Answer:
Step-by-step explanation:
8x² - 5x + 3x(4 - 2x) =8x² - 5x + 3x*4 - 3x*2x
= 8x² - 5x + 12x - 6x²
Now add the like terms
= 8x² - 6x² - 5x + 12x
= 2x² + 7x
First you do 7.9/ 1/4, that gets you 1.975. that is how much blue paint there is. Then you do 7.9-1.975= 5.925, which is how much white paint she used. So in total she used 1.975 pints of blue paint, and 5.925 pints of white paint.
66x is the correct answer

Sin D = 13 sqrt3/26 = 0.76
Sin E = 13/26 = 0.47
Cos D = 13/26 = 0.87
Cos E = 13 sqrt3/26 = 0.64
