Answer:
s = 1.35 (See explanation!)
Step-by-step explanation:
To write an equation, you need to know that all four sides of a square are equal. Since each side is equal, it can be represented by the same variable or value. I'll use s for the variable:
Equation:
4s = 5.4
Note: the 4s is the total perimeter (4 * side)
Now, solve:
4s = 5.4
Divide by four to isolate the s:
4s/4 = 5.4/4
Finally:
s = 1.35
Answer: B
Step-by-step explanation:
Answer:
10
Step-by-step explanation:
If ABCD is a rectangle, then AB=CD and AC=BD.
- AC=BD, so x+6=2x-4
- Subtract, -x+6=-4
- Subtract, -x=-10
- Make positive, x=10
Check work:
- 10+6=2(10)-4
- 10+6=20-4
- 16=16
