Answer:
<u>x = 5</u>
Step-by-step explanation:
Equating the terms :
Add 2 on both sides :
- x + 3 + 2 = 2x - 2 + 2
- x + 5 = 2x
Subtract x from both sides :
- x + 5 - x = 2x - x
- <u>x = 5</u>
the answer is 29363

Answer:
180degrees
Step-by-step explanation:
Given the expression cos^2x - cos x - 2 = 0
Let P = cos x
P^2 - P - 2 = 0
Factorize
P^2 - 2P + P - 2 =0
P(P-2)+1(P-2) = 0
P-2 = 0 and P + 1 = 0
P = 2 and P = -1
Since P = cos x
cos x = -1
x = arccos(-1)
x = 180degrees
Hence the require angle is 180degrees
Answer:
2/5
Step-by-step explanation:
5+4+1 = 10. If you have 4 nickels out of 10 coins, it means there is a 4/10 chance of selecting one, but to simplify, 2 is the greatest common factor, so you would divide each number.
4/2 = 2.
10/2 = 5.
The answer is 2/5.
