A=7 is what I got since this was a equation problem
38.4 is the area. it’s 8.5 ft long so you do 8.5x2 and you get 17, and then for 10.7 you do 10.7x2 and get 21.4, then you add 21.4 and 17 together.
Hello,
The method is to find the roots of the denominator.
x²-2x-15=x²+3x-5x-15=x(x+3)-5(x+3)=(x+3)(x-5)
Roots are x=-3 and x=5
Answer C
Multiply by distribution:
6x³ - 6x² - 12x - 18x² + 18x + 36
Combine like terms:
6x³ - 24x² + 6x + 36
The correct choice is the first choice.
