Answer:
x=-3
y=3
(-3-3i)(3+5i)
Step-by-step explanation:

and we have that must equal
6-24i
3x+5y=6
5x-3y=-24 and if we work it we found out that the solutions are
x=-3 and
y=3
Answer:

Step-by-step explanation:
For this case, the first thing you should do is multiply the rate of decrease by time.
We have then:
(3.6 × 10-2) * (1.8 × 104)
= 648 mm
We are going to convert this number into scientific notation:
= 6.48 * 10 ^ 2 mm
Rounding we have:
= 6.5 * 10 ^ 2 mm
