Answer: -1m²+81

Step-by-step explanation:

correct standard form means that the terms are ordered from biggest exponent to lowest exponent.The leading coefficient is the coefficient

of the first term in a polynomial in standard form.

FoR example, (9+ m) (-m+9) = *(m+9) (-m+9) *m(-m+9) +9 (-m+9)* -1.mm+9m +9(-m+9) * -1m² +9m +9(-m+9) *-1m²+9m- 9m +81

answer -1m²+81

Your friend has a recipe book with 1000 recipes.she makes 2 new recipes each week. after 1 year, what fraction of the recipes ha
adoni [48]

After one year, the fraction of the recipe that she has not made is 896/1000 or 112/125

Fraction:

A fraction means the part of the whole thing.

For example, a pizza is divided into four equal pieces, then each piece is represented by ¼.

Given:

Your friend has a recipe book with 1000 recipes.

She makes 2 new recipes each week.

We need to find the fraction of the recipes has she not made after one year.

We know that,

1 year = 52 week

So, here they given that she will make 2 recipes per week.

So, in one year she will make

=> 2 x 52 = 104

So, the remaining recipes in the book is

=> 1000 - 104

=> 896

So, the fraction is

=> 896 / 1000

When we simplify it, then we get

To simplify, we need to find the Greatest Common Factor (GCF) of 896 and 1000, if it exists, and reduce our fraction by dividing both numerator and denominator by it. GCF = 8, and getting our simplified answer:

=> 112 / 125
