Answer: A. -17 , 19
Step-by-step explanation:
Move all terms to one side.
z^2-2z-323=0
z^2 −2z−323=0
Factor : z^2-2z-323
z^2−2z−323.
(z-19)(z+17)=0(z−19)(z+17)=0
Solve for z.
z=19,−17
Answer:
6z + 9
Step-by-step explanation:
distribute 3/4 by 8z to get 6z
distribute 3/4 by 12 to get 9
Yes, if the rule is
... output = input + 12
you add 12 to whatever input value you might have. For an input of 6, this is
... output = 6 + 12 = 18
P = 2(l+w)
substitute in the knowns
90 = 2(27+w)
divide by 2
90/2 = 2/2 *(27+w)
45 = 27+w
subtract 27 from each side
18=w
w = 18ft
