.4
Answer:
See Below.
Step-by-step explanation:
Problem 1)
We want to simplify:
First, let's factor the denominators of each term. For the second term, we can use the difference of two squares. Hence:
Now, create a common denominator. To do this, we can multiply the first term by (<em>a</em> + 1) and the second term by (<em>a</em> + 2). Hence:
Add the fractions:
Factor:
Simplify:
We can expand. Therefore:
Problem 2)
We want to simplify:
Again, let's create a common denominator. First, let's factor out a negative from the second term:
Now to create a common denominator, we can multiply the first term by (<em>a</em> - <em>c</em>) and the second term by (<em>a</em> - <em>b</em>). Hence:
Subtract the fractions:
Distribute and simplify:
Cancel. Hence:
The equation is y= (5/2)x - 29. Hope this helps
For this case we have that by definition, the GCF or (Greatest Common Factor) is given by the greatest common factor that divides both terms without leaving a residue.
15: 1,3,5,15
3: 1.3
Then we have the GCF of the expression is:
ANswer:
Option C
The total amount that all the angles inside the triangle equal is 180°.
So you can write an equation with the given
3x+5 + 2x+18 + 2x+17 = 180
Combine all like terms
7x + 40 = 180
subtract 40 from both sides
7x = 140
divide both sides by 7
x = 20
Then you plug that into the angles and find out how much each is
3x + 5
3(20) + 5
60 + 5
65
2x + 18
2(20) + 18
40 + 18
58
2x + 17
2(20) + 17
40 + 17
57
Hope this helps :)
