For rectangles, we know that there are two of each measure (length and height). If the length is four times the width, then this means l = 4w. Because there are two of each, it becomes 2 * (4w), which represents the two length measures. Now we also have two width measures, which is 2w. The phrase 'at most' hints at to perimeter being greater than or equal to something.
The answer is 
First, write it as an equation
2.50+3x=5.05
Next, subtract 2.50 from both sides
2.50-2.50+3x=5.05-2.50
3x=2.55
Divide 3 on both sides
3x/3=2.55/3
x=0.85

Answer:
True
Step-by-step explanation:
-8-5b+7+5b
add +5b to -5b to get 0.
-8+7 = -1
Answer is -1.
x = 3 - (3×6) + 2. We perform the operation in the bracket first.
x = 3 - 18 + 2
x = -15 + 2 = 2 -15 = -13
x = -13
