Answer:
The expression will be 
Step-by-step explanation:
We have given expression 
We know the property of exponent that when two function are divided then the power of exponent is subtracted and when there is multiplication of two function then exponent is added
So
So the expression will be 
The area model you can use is D , cs 70 +3 & 30+9
Answer:
9 units.
Step-by-step explanation:
Let us assume that length of smaller side is x.
We have been given that the sides of a quadrilateral are 3, 4, 5, and 6. We are asked to find the length of the shortest side of a similar quadrilateral whose area is 9 times as great.
We know that sides of similar figures are proportional. When the proportion of similar sides of two similar figures is
, then the proportion of their area is
.
We can see that length of smaller side of 1st quadrilateral is 3 units, so we can set a proportion as:




Take positive square root as length cannot be negative:


Therefore, the length of the shortest side of the similar quadrilateral would be 9 units.
