Answer:

Step-by-step explanation:
You first equate it to zero to get:

Then solve using square root method




Or


Now work it backwards


Hence the factored form is:

Answer:
No
Step-by-step explanation:
the salesman's claim is false because the new machine only makes 20 items an hour and the old one makes 25. So in 8 hours the new machine will only make 160 items and the old one will make 200
A²+b²=c²
39²+b²=89²
1521+b²=7921
subtract 1521 from both sides
b²=6400
so then you square both sides
√6400
80
Answer:
Step-by-step explanation:
10x + 8y = -18
-8x - 8y = 24
2x = 6
x = 3
8(3) + 8y = -24
24 + 8y = -24
8y = -48
y = -6
(3, -6)
