L +2w = 500
a = lw
a) l = 500 -2w
.. a = (500 -2w)*w
b) The zeros of the above equation are w=0, w=250. The vertex of this quadratic is on the line of symmetry, halftway between the zeros, at w=125 ft.
c) a = (500 -2*125)*125 = 31,250 . . . . square feet
Answer:-18/15
Step-by-step explanation:
15g+18=0
15g=-18
divide both sides by 15
g=-18/15
Length of Triangle= 2(W) +2
i dont know if im right or not.
(Add5) 1/9..(add 7) 1/16... (add9) 1/25... (add 11) and get -> 1/36
the correct answer should be (b) 6 is extraneous.
If you look at the second row of the solution you see (x-6) as a factor in one of the denominators. That's a problem: if 6 were a solution this denominator would become 0. But denominators being 0 is bad (undefined), so while 6 comes out of the algebraic manipulation as a solution, it is invalid, or extraneous.
-3 is a fine solution.
