If you were to factor you would do what my teacher likes to call reverse foil so it would look like this (x-9)(x+4) so what you do is you brainsrorm to see what multiplies what to get that and 9*4=36 so that is how you factor -36 to find the -9
Hope this helps if I'm correct if not I will try to find the answer
Answer:
Standard Form: y = 4(x-1)(x+5)
Step-by-step explanation:
4 is the leading coefficient, so it should go in front. When making a standard quadratic equation, you must do the opposite for each of the roots (negative to positive, positive to negative.)
if you’re asking for a general form quadratic equation, then sorry, I am unable to help you with that :(
Answer:
Divide
Step-by-step explanation:
im think you have to divide to find the height of the cylinder.
625 divide 9 = 69.44
Answer:
66. Assuming after you substituted 3 in place of x, you followed order of operations, or PEMDAS.
Step-by-step explanation:
6(2x) + 9x +3 = area
6 (2(3)) + 9(3) + 3 = area
6 x 6 + 27 + 3 = area
36 + 30 = 66
area = 66
