Hi, I would be glad to help you here.
<span>7x − 2 < 3 + 2x
Move terms
7x - 2x - 2 < 3
Collect the like terms
(7x - 2x) = 5x (<3 + 2 stays the same)
Calculate
5x (<3 + 2 = 5)
5x <5
Divide both sides of the inequality by (5) giving you,
x < 1
So, finally in a total the correct answer here is (x < 1)

Step 1: Let a = b.
Step 2: Then a^2 = ab ,
Step 3: a^2 + a^2 = a^2 + ab ,
Step 4: 2a^2=a^2 + ab,
Step 5: 2a^2 - 2ab = a^2 + ab - 2ab,
Step 6: and 2a^2 - 2a^b = a^2 + ab - 2ab .
Step 7: This can be written as 2(a^2 - ab) = 1(a^2 - ab) ,
Step 8: and cancelling the (a^2 - ab) from both sides gives 1 = 2.</span>
Answer:
No.
If two rectangles are congruent, it means they are the exact same shape and size.
I have uploaded an image with this answer. In the image, you can see two rectangles with the same perimeter. However, they are not congruent because they are not of the same size (even though they are of the same shape - a rectangle).
Hence, two rectangles may not be congruent if they have the same perimeter.
