The length of each side of the larger square is 8 cm.
<u>Step-by-step explanation</u>:
Step 1 ;
- The combined area of two squares = 80 sq.cm
- The side of small square = x
- The side of larger square = 2x
Step 2 :
Area of the square = a^2
Area of small square + area of large square = 80
x^2 + (2x)^2 = 80
x^2 + 4x^2 = 80
5x^2 = 80
x^2 = 80/5
x^2 = 16
x = ±4
Step 3 :
Since length cannot be negative, the value of x= 4
∴ The length of the side of small square = 4cm
The length of the side of larger square = 2x = 8cm
Yes, Lets look at
2x=x
In order to move the x over to the other side of the equation, we will have to subtract it.
This means our equation will now look like:
x=0
Another example:
-x=9x
Now that the x is negative, we have to do the opposite of a negative, which is a positive, which means we would have to add an x on both sides.
Our equation will now look like:
0=10x
We are given that <span>Ellie had 44 books in her bookcase. She counted 32 fiction books, thus she has nonfiction book of about,
Nonfiction= 44-32= 12
Thus, Ellie has 32 fiction books and 12 nonfiction books. But we are tasked to find the ratio of the of fiction books to nonfictions books. This gives us,
32:12
Reducing 32:12 into simpler ratio by factoring 4 on both sides,
32:12=8*4:3*4=8:3
Therefore, Ellies Bookcase has a fiction to nonfiction ratio of 8:3 which is letter A.</span>

I hope you see the pattern here . When multiplying the exponent (the small number near the 10) determines the number of zeros to the RIGHT . When dividing the number determines how many zeros to the LEFT usually resulting in a decimal. This is called scientific notation.
Hope this helps!:)
To solve this the first thing you do is the () so 68+7=75. Next you do 75+93=168. I hope this helped. :) Brainlest answer?
