Step-by-step explanation: 3(1)+k =8 8-3=5
Find lengths of quadrilateral sides:
,
,
,
.
Since all sides have the same lengths, you can state that this quadrilateral is rhombus.
Let's check whether quadrilateral JKLM is a square. To check this let find the lengths of diagonals:
,
.
The lengths are different, so quadrilateral is not a square.

Step-by-step explanation:
Answer:
Step-by-step explanation:
4) A photograph costs $20, so the cost of x photographs is 20x.
Similarly, the cost of y prints is $25.
So the total cost is 20x+25y, and this has to be less than or equal to 400, so C.
5) just plug each pair in.
For example for the first option, x=5 and y=10, and since 20(5)+25(10)=100+250. which is less than or equal to 400, it works.
