Well,
We can see that there are 8 10's and 3 1's. So we can write 8 10's followed by 3 1's and join them with addition symbols.
83 = 10 + 10 + 10 + 10 + 10 + 10 + 10 + 10 + 1 + 1 + 1
1: Trapezoid
2: rectangle!
STEP BY STEP EXPLINATION
A right angle is exactly 90 degrees, so if the pentagon has 108 degree angles, it’s not a right Angle!
The parallelogram has 107 degree angles and 73 degree angles, it’s not exactly 90.
The trapezoid has two right angles! The two sides make a right angle at the vertex! So, it has a right angle!
Same thing for the rectangle!
HOPE THIS HELPS! HAVE A GREAT DAY!
4x+1=2x-5
you need to isolate the x on one side so
4x+1=2x-5
-4x -4x (you need to subtract 4x by both sides of the =)
so you get
1=-2x-5
so now you need to keep simplifying now you need to subtract the five from both sides
1=-2x-5
-5 -5
-4=2x
now divide the 2 on both sides
-4=2x
/2 /2
-2=x
answer x = -2

Step-by-step explanation:
The area of a square is the square of the side length.
For example, (√125)² = 125.
__
The side length of a square is the square root of the area.
For example, √98 = √(7²·2) = 7√2.
