Answer:
x5y2−x2y4
Step-by-step explanation:
There are no like terms. Therefore the answer is correct. =x^5y^2−x^2y^4
8 x 2 + 6x + 5=0
16 + 6x + 5=0
6x+21=0
6x+21-21=0-21
6x=-21
6x/6=-21/6
x=-7/2
The first digit may be 1 or 8.
The second digit may be 1, 2, 4, 8.
The third digit may be 1, 3, 5, 7, 9.
There are 
The probability that this is the correct code is 
The answer is n^4. This is calculated by just subtracting the exponents. Hope this was what you were asking.
Answer:
You would do this problem like a normal varible problem. x=10
Step-by-step explanation:
Since 9x is a right angle the inside would also be 9x
9x+4x+10+40=180
180 because that is how much a triangle equals
combine like terms
13x+50=180
subtract 50 from both sides
13x=130
divide by 13
x=10
