Answer:
I believe the answer is -6/10 or -0.6
Step-by-step explanation:
-2.1- (-0.6) = -1.5
-1.5 = -1 1/2
Weird question wording. I take it should mean that this is a quadratic equation with solutions of x = -5 and x = 8. Then these are the factors: (x+5) and (x-8).
So
(x+5)(x-8) = 0 is the equation because x = -5 and x = 8 can make left-side equal to 0. But we expand so it becomes x² - 3x - 40 = 0
The equation for the area of a circle (as most drums are) is
A= π · r²
so knowing the radius to be 14, plug that in for r and A=196π, or about 615.4 inches squared
