Answer:
x²y²+xy²+3+xy+2y²
Step-by-step explanation:
(2x²y²+x²y+xy²+3)-(x²y²+x²y²+x²y-xy-2y²)
1. remove the parentheses (when there’s - in front of an expression in parentheses change the sign of each term of the expression)
2x²y² + x²y + xy² + 3-x²y² - x²y² - x²y + xy - 2y²
2. eliminate the opposites
2x²y² + xy² + 3 -x²y² + xy +2y²
3. collect like terms
x²y² + xy² + 3 + xy + 2y²

Convert 253 into a hexidecimal
Answers
Answer:
0xFD
Step-by-step explanation:
To convert 253 into hexadecimal, divide the number by 16 repeatedly and record the remainders.
Explanation:To convert 253 into hexadecimal, you need to divide the number by 16 repeatedly and record the remainders. The most significant digit of the hexadecimal representation will be the last remainder obtained. So, let's proceed:
253 divided by 16 is 15 with a remainder of 13 (D in hexadecimal).15 divided by 16 is 0 with a remainder of 15 (F in hexadecimal).Therefore, 253 in hexadecimal is DF.

Below is the graph of equation y= |x+2|-1. Use this graph to find all values of x such that...
y<0
Answers
To find the values of x such that y is less than 0 in the equation y = |x + 2| - 1, we set y less than 0 and solve for x. The values of x that satisfy y < 0 are x < -1.
Explanation:To find the values of x such that y is less than 0, we need to determine the portion of the graph below the x-axis, since y is negative in that region. Given the equation y = |x + 2| - 1, we can set y less than 0 and solve for x.
Setting y = 0, we have 0 = |x + 2| - 1. Adding 1 to both sides, we get 1 = |x + 2|. When the expression inside the absolute value is positive, the absolute value will be the same. Therefore, we can write x + 2 = 1. Solving for x, we get x = -1.
So, the values of x such that y is less than 0 are x < -1.

The number of dogs in a city is declining at a rate of about .08% each
year. If there were 3500 cats to begin with, how many will there be in 10
years?
Answers
Answer:
There will be 3472 cats in 10 years
Step-by-step explanation:
There were 3500 cats
The number of dogs in a city is declining at a rate of about 0.08% each year.
We are supposed to find the no. of cats in 10 years
Formula :[tex]N(t)=N_0(1-r)^t[/tex]
Where N(t) = Remaining cats after t days
[tex]N_0[/tex] = Initial population
r = rate of depreciation
t=time
So, No. of cats remained after 10 years = [tex]3500(1-\frac{0.08}{100})^{10}=3472.100[/tex]
Hence There will be 3472 cats in 10 years

How would I find x, I know it's an isosceles triangle but I so not know how to solve for it?????
Answers
Answer:
x=7 (if your teacher cares it could + or - 7)
Step-by-step explanation:
Okay, since it's a 90 degree triangle you can use the Pythagorean theorem
( a^2 + b^2 = c^2)
Since it's an isosceles triangle the other side is x because it's the same value.
x^2 + x^2= (7[tex]\sqrt{2}[/tex] )^2
Add the left side
2x^2= 7^2 + [tex]\sqrt{2}[/tex]^2 roots and square roots cancel each other out
So -> 2x^2= 49 x 2 =98
just solve for x.
x^2 = 98/2
x^2= 49
Square root both sides
x= 7

Six words have 2 vowels and 2 consonants .How many letters are there in 6 words?How many vowels consonants
Answers
Answer:
24, 12, 12
Step-by-step explanation:
I do not understand the question, but I believe you gave us how many vowels and consonants are in a word. Then you asked us for how many of them were in 6 words, which is simple math of 4 times 6. I don't get the last part, but I think you asked how many consonants in 6 words, and how many vowels in six words, another simple math question, 2 times 6.
In the English language, 5 letters are typically considered vowels: a, e, i, o, and u, with 2 additional letters, y, and w, that can sometimes act as vowels or consonants depending on their position in a word. To find out how many vowels and consonants there are in six words, we need more information about the specific six words.
Explanation:In the English language, 5 letters are typically considered vowels: a, e, i, o, and u. However, there are 2 additional letters, y, and w, that can sometimes act as vowels or consonants depending on their position in a word.
To find out how many vowels and consonants there are in six words, we need more information about the specific six words. If each of the six words has 2 vowels and 2 consonants, then the total number of letters in the six words would be 6 x (2 + 2) = 24.

Joe wants to buy a skateboard but he doesn't know if he has enough money. The price of the skateboard is $85 and the sales tax is 6%. What will be the total cost of the skateboard?
Answers
Answer:
$90.10
Step-by-step explanation:
price of the skateboard = $85
sales tax = 6%
Dollar value of sales tax = 6% of price of the skateboard
= 6% of $85 = (6/100) * $85 = ( 6* 85)/100 = $ 5.10
Total cost of the skateboard = price of the skateboard + sales tax value
substituting the value of price of the skateboard and sales tax value, calculated above, we have
Total cost of the skateboard = $85 + $ 5.10 = $90.10
