Answer:
Q1, Q2 and Q3 are all congruent.
Step-by-step explanation:
As quadrilaterals are drawn on a Cartesian graph, it is easy to see that Quadrilateral−1, Quadrilateral−2 and Quadrilateral−3 are all congruent, while Quadrilateral−4 is different.The sides of Quadrilateral−1, Quadrilateral−2 and Quadrilateral−3 can be found using Pythagoras theorem and are {2,2,√10,√2} units. Even corresponding angles as well as diagonals two are congruent in these three quadrilaterals.Naming them as Q1, Q2, Q3 and Q4 respectively, we can say that pair wise Q1≡Q2, Q2≡Q3 and Q1≡Q3

Step-by-step explanation:
The area of a rectangle is obtained by multiplying its lenght by its width.
You know that the area of this rectangle is , then you need to apply the Difference of squares to find the dimensions of this rectangle.
Remember that the Difference of squares is:
Then, applying this, you get:
Therefore, now you know that the dimensions are:
and

Step-by-step explanation:
Answer:
x = 3
Step-by-step explanation:
Step 1: Write out equation
16 = 9x + 4 - 5x
Step 2: Combine like terms
16 = 4x + 4
Step 3: Subtract 4 on both sides
12 = 4x
Step 4: Divide both sides by 4
3 = x
Step 5: Rewrite
x = 3
