Answer: <u>Rational</u>
Step-by-step explanation: Let's first go over what a rational number is. A rational number is any number that you can write in the form
where a and b are integers and b ≠ 0.
The fraction
would be a rational number because it's in the form of
. Therefore, 2/9 is a rational number.
The length of the SMALLER square is:
B. 5
Basically I tested each answer choice and see if all the information matches it.
Lets check how my answer is correct:
We know that:
The length of the bigger square is 3 more than the smaller square’s length.
The areas of both squares add up to 89 cm^2
length of the SMALLER square is: 5 cm
length of the LARGER square:
5 + 3 = 8 cm
Area of smaller square:
5^2 = 25 cm^2
Area of bigger square:
8^2 = 64 cm^2
ADD UP BOTH AREAS OF SQUARES:
25 + 64 = 89 cm^2
Hope this helps!
To check you can set the ratios up as fractions, then cross multiply.
If they equal the same thing they are proportional, if they don't, they are not.
<u> 25</u> = <u>5</u>
16 4
Cross multiply (25)(4) = (16)(5)
100 = 80
Since 100 does NOT equal 80 the ratios are NOT proportional.
