Answer:
x=7, x= -2
Step-by-step explanation:
- Start by putting the whole equation to one side: x2-5x=14 ----> x2-5x-14=0
- Next, factor the equation: x,x -7,2 ----> (x-7)(x+2)=0
- Now, solve both equations: x-7=0....x=7 AND x+2=0.....x= -2
- Plug both in to make sure that they are correct....both are correct
Step 1- Simplify brackets
c + 4 - 3c -2 = 0
Step 2- Simplify c + 4 - 3c -2 to -2c + 4 - 2
-2c + 4 - 2 = 0
Step 3- Simplify -2c + 4 - 2 to 2c + 2
-2c + 2 = 0
Step 4- Subtract 2 from both sides
-2c = -2
Step 5- Divide both sides by -2
Answer: c = 1
Answer:
A. X = 30º
Step-by-step explanation:
The angle labeled x & the right angle are vertical angles to the one labeled 120º.
Therefore:
X + 90 = 120
Solve for x:
X + (90-90) = 120 - 90
X = 30
Hope this helps! Have a great day!
Hello.
There is only one solutin for <span> x^2 + 10x + 25 = 0
You can tell because it ends with a 0.
Have a nice day</span>
