1 answer:
You have to find the LCD or least common denominator.
In this case the LCD would be (x-6)(x+5).
Problem: x/ x-6 - 1/x+5
Step 1: multiply x-6 to the numerator and denominator of 1/x+5
1(x-6)/ (x+5)(x-6)
Step 2: multiply x+5 to the numerator and denominator of x/x-6
x(x+5)/ (x+5)(x-6)
After all that, this is how the problem should look now
x(x+5)/ (x-6)(x+5) - 1(x-6)/ (x-6)(x+5)
If you simplify this you get
x²+5x-x+6/ (x-6)(x+5)
If you subtract both 5x-x (like terms) you get
x²+4x+6/ (x-6)(x+5)
which is the answer

Answer:
8 and 25
Step-by-step explanation:
We can set up an equation to help solve this problem.
Let x represent the smaller number
x+(x+17)=33
2x+17=33
2x=16
x=8
The smaller number is 8
Add 17 to 8
The larger number is 25
(-1,-2) That is the answer to your question.
Answer is C. Reflection in the line y=x
Hmm a number as. a decimal is 1/2=0.50
I have to go with True because a Rhombus is a Square.
