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

What is 8,792 as a fraction?

Wittaler [7]

We have a number $8.792$ .

To write it as a fraction first count the number of decimals and call it $n$ (which, in our case, has a value of 3). Multiply the number with $10^n$ to get $8792$ . Then divide this number by $10^n$ to get $\frac{8792}{10^n}$ from here you can either simplify (if the assignment says so, then the simplified fraction is $\frac{1099}{125}$ ) or not.

Hope this helps.

Susan had 8/9 acres of land. She planted 2/5 of it with corn. How many acres did she plant with corn?

Sergio039 [100]

$\bf \textit{how much is }\frac{2}{5}\textit{ of }\frac{8}{9}?\implies \cfrac{8}{9}\cdot \cfrac{2}{5}\implies \cfrac{16}{45}$

that's how many acres she planted with corn.
