A:C
Step-by-step explanation:
0.2 is the same as 2/10
18/(2/10)
As you may have learned in school, when you divide a fraction, you flip the fraction in the denominator, and change it to multiplication
18/(2/10) becomes 18 x (10/2)
multiply normally
18 x 10 = 180
divide to find answer
180/2 = 90
90 is your answer
hope this helps
Remember, when you meet this problem, flip the second fraction, and change the division sign into multiplication. (always second, never first (if first is a fraction)).
A graphing calculator can help find the number(s) that meet this requirement.
The number could be 15, or -14.
The quadrilateral is a square
<h3>What are quadrilaterals?</h3>
Quadrilaterals are polygons, that have four sides and four corners
The coordinates are given as:
- A = (3, 5)
- B = (5, 2)
- C = (8, 4)
- D = (6, 7)
Start by calculating the adjacent side lengths using:

So, we have:




The side lengths are equal.
Hence, the quadrilateral is a square
