answer choice a
x^2 - 5x - 1 = 0
a=1, b=-5, and c=-1
next you plug in the numbers into the quadratic formula
-(-5) plus or minus the square root of (-5)^2 - 4(1)(-1)/ 2(1)
after you simply, you should get 5 plus or minus the square root of 29, which is answer choice a
I believe the answer is c
The expression would be (w divided by 1/8) - 2
Answer:
14/3 or 4 2/3
Step-by-step explanation:
2 ÷ 3/7 can be written as 2/1 ÷ 3/7 (2 divided by 1 is still 2)
When dividing fractions we use KFC
- Keep the first fraction the same
- Flip the second fraction
- Change the sign from ÷ to ×
So:
2/1 ÷ 3/7 becomes 2/1 × 7/3
We can now multiply the fractions by multiplying the numerators and denominators together:
2 × 7 = 14
1 × 3 = 3
Answer: 14/3 (this can also be written as 4 2/3)
Hope this helps!
