time 2nd 5/5 it become 35/5x-20
2/5x-20+35/5x-20
=37/5x-20

<em>Answer: B. It is a perfect square</em>
Step-by-step explanation:
<u>Radical Expressions</u>
Melissa multiplied 
and 
and got a rational number.
We are also given that a and b are both natural numbers. It means their product must be not only rational but also a natural number.
We can write that product like:
If the result is a natural number, then the product of a and b must be a perfect square. so the radical disappears.
Answer: B. It is a perfect square
Answer:
70
Step-by-step explanation
110/55 =2 35*2=70 also i done the ixl thing and it said it was correct
Answer:
(0,-2)
Step-by-step explanation:
one way to solve...
3x - y = 2 --> *4
-2x + 4y = -8
multiply the first equation by 4
12x - 4y = 8
-2x + 4y = -8
-----------------
10x = 0
x = 0
y = -2
this method is called elimination
another way to solve...
3x - y = 2 simplify for y to get y = 3x - 2
-2x + 4y = -8 substitute y into this equation to solve for x
-2x + 4(3x - 2) = -8
-2x + 12x - 8 = -8
10x = 0
x = 0
y = -2
substitution
alsoo if there are options, just plug in the numbers to the correct variables
The GCF is a number you can get out of these 2 numbers that can later be multiplied to get the same thing as teh biginning for example lets try 16 it fits on 32 2 times nad in 16 once this means that this is equal to 16(2+1) when you multiply doe sit give you 32+16 it does so 16 is your GCF
Hope this helps
