When multiplying numbers a negative number will make a positive into a negative. Yet if multiplied again by another negative it will cancel out or make it positive again. Seeing as answer c has only one negative it's the correct answer.
Area=3.14(r)^2
radius is half of diameter
3.14(9.5)^2=283.385
rounded is 283.39
<u>Answer:</u>
The answer is c = 
<u>Solution:</u>
When a sum of two numbers is multiplied by a number, the number can be distributed to the addends separately, then adding the products together will produce the same result as multiplying sum by the number. This property is called distributive property of multiplication.
To find the value of, a(c-b)=d
On applying the distributive property of multiplication which is ![[a\times(b+c)=a\times b+a\times c]](https://tex.z-dn.net/?f=%5Ba%5Ctimes%28b%2Bc%29%3Da%5Ctimes%20b%2Ba%5Ctimes%20c%5D)
Here we get,

So the equation will be,




Answer:
800
Step-by-step explanation:
First do 20x20 (20 lines x 20 words per line) to get 400
Then multiply 400 by 2 (400 times both pages) to get 800 which is how many words Claire's report should be.
