You have to use distributive property. Multiply the numbers outside of the parenthesis by the numbers inside. For example, you would multiply 0.4 by 2x first, then multiply it by 1/2. You should get two answers. Write them down in this form: first answer + second answer. Then do the same for the other side of the equal sign, but leave the - 4 alone. If you need more help, let me know
Your basically building a new equation with the two functions given to you.
(sqrt(3x + 7)) + (sqrt(3x - 7)) = 0
Then just open up the brackets and simplify further.
sqrt(3x + 7) + sqrt(3x - 7)= 0
Nothing to special really happened there, just removed the brackets. Now you move one of the radicals to the other side so you can square the whole equation.
sqrt(3x + 7) = - sqrt(3x - 7)
Then go ahead and square both sides to remove the radical.
3x + 7 = 3x - 7
Now if you kept trying to isolate x, you find that both sides will just cancel each other out and you are left with,
7 = -7
Since that statement isn't true your answer will be that there is no solution to this equation.
x ∈ Ø
Answer:
The answer is B.
Step-by-step explanation:
Answer:
0
Step-by-step explanation:
63/7 = 9
We know,
If any number smaller then fifty told to be rounded to its nearest hundred then the answer is ' 0 '
Similarly the nearest hundred of 9 is 0.

Answer: PTR = 80°
PTQ= 45° PTS= 128°?
Step-by-step explanation:
See angles <ptr <ptq <pts ar based off of the number of degrees on the protractor
