Answer:
70
Step-by-step explanation:
10x7=70
$200-10.50x = $50
200-50=10.50x
150=10.50x
14.29=x
so you can order 14 boxes.
Answer:
k=-2
Step-by-step explanation:
11k - 16 - 2k = 17k
11k- 2k -17k=16
-8k=16
k=16/-8
k=-2
hope it helps u
What the statement means is that x^2 + kx + 2k = 0 when x = -3. That's because x + 3 will equal zero
(-3)^2 + (-3k) + 2k = 0
9 - 3k + 2k =0
9 - k = 0
9 = k
Check
=====
x^2 + 9x + 18 = 0
(x + 3)(x + 6) = 0
These are the two factors. As expected from the givens one of them is (x + 3)
