i think the answer is -3 & 3
Answer:a
Step-by-step explanation:
it is 2.2360679775 which is in between 2.01 and 2.24
1.65
You can substitute in the values of p, n and e to get the equation:
5700 = 4000c - 900
add 900 to both sides and you get
6600 = 4000c
divide both sides by 4000 and you get
1.65 = c
so the answer is 1.65
X+y = -2 is the same as y = -x-2 when you subtract x from both sides
x+y = -2 is the same as 2x+2y = -4 when you multiply both sides by 2
So A, B, and C are the same equation just in a different form.
Answer: Choice D) any of the above
