Find the domain of the rational expression.
f(x) =
8x - 3
——————
(x + 5)(x-7)

What number should be added to both sides of the equation to complete this square? x^2-10x=7

Enter the number of complex zeros for the polynomial function in the box. f(x) = x+ + 5x² +6

Which mathematical statements are true? 1) if 3 is an odd number, then 3 times 3 is an even number. 2) if 6 is less than 7, then 4 is greater than 7. 3) six is divisible by 3, and 10 is a multiple of 2. 4) the average of the data is greater than the largest value in the data, or it’s less than the largest value in the data. 5) the slope of a linear graph is its rate of change, and the graph’s y-intercept is the initial value. 6) if an equilateral triangle has equal angles, then all its angles will measure 45°.
