Sqrt(1-3x)=x+3
[sqrt(1-3x)]^2=(x+3)^2
1-3x=(x+3)(x+3)
1-3x=x^2+6x+9
-3x=x^2+6x+8
0=x^2+9x+8
The answers are -1 and -8 BUT, we have to plug them back into the original equation to make sure we don't get a negative under the square root sign.
After doing this, we realize that only -1 works, so the answer is x=-1
Sorry that this took forever to answer. I was thinking of a good way to explain this, and if you need any further explanation, message me:)
Best wishes:)
Answer:
x = 5, x = 1
Step-by-step explanation:
Hello!
We can solve this quadratic by factoring.
<h3>
Solve</h3>
Use the zero product property:
- x - 5 = 0
x = 5 - x - 1 = 0
x = 1
x = 5, or x = 1

Answer:
x= 50
Step-by-step explanation:
the total measure of all the angles of a triangle is always 180 so you subtract 65 two times (once for each of the other angles) and that will ive you the remaining degrees which in the case would be x.
1. 180 = triangle
2, 180- 65- 65= 50
3. x=50
