Answer:

c.

Step-by-step explanation:

2x² - 4x - 3 = 0

x= \frac{-b+/-\sqrt{b^{2}-4ac} }{2a} \\\\x= \frac{-(-4)+/-\sqrt{(-4)^{2}-4*2*(-3)} }{2*2} \\\\x= \frac{4+/-\sqrt{16+24} }{4} \\\\x= \frac{4+/-\sqrt{40} }{4} = \frac{4+/-2\sqrt{10} }{4}=\frac{2+/-\sqrt{10} }{2}

If someone sleeps 8 hours a day for 75 years how many hours did that person sleep in his lifetime?
ra1l [238]
The person sleeps 8 hours a day.

There are 365 days in a year and 366 days in a leap year.

A leap year occurs every 4 years.

If we divide 75 by 4, we get 18.75. This number represents how many leap years occurred in 75 years. So, the person experienced approximately 19 leap years.

19 leap years has 6954 days.

The other 56 years, which have 365 days each year, have a total of 20,440 days.

That's a total of 27,394 days.

27,394 × 8 = 219,152 hours

This is approximately 24 years or 9,131 days.

Can you please show me the steps and solution to this problem?
ANEK [815]
M = - 7 - 3 / - 2 - 4
m = - 10 / - 6
m = 10/6
m = 5/3

y = 5/3x + c , (4,3)
3 = 5/3(4) + c
12 = 20 + 4c
4c = - 8
c = - 2
y = 5/3x - 2

How do you divide 2/10 by 3/4? Please help!
Ray Of Light [21]

Answer:

8/30

Step-by-step explanation:

Dividing fractions is almost the same as multiplying to do it you just have to flip the second fraction and change the division sign to a multiplication sign like this,

2/10×4/3

then from there, you have to multiply the top numbers and the bottom numbers

2×4=8

10×3=30

then put them together

8/30

IF YOU HELP ILL GIVE YOU BRAINLY PLEASE!!
irinina [24]

Answer:

part a:

x lengths = 6

unit lengths = 2

part b:

6x+2

Step-by-step explanation:

You add the like terms, in this case, there are 6 x, so we have 6x, and two 1s, so 1+1= 2, and since 6x and 2 are not like terms, we can't add them, making our answer 6x+2
