The expression that represents the perimeter of the rectangle is 4x² + 14x - 3 = 0
<h3>How to determine the expression</h3>
The formula for perimeter of a rectangle is given as;
Perimeter = 2 ( length + width)
Let the length of the rectangle be x
Width of the rectangle be y
From the information given, we have that;
y = 4 - 3/4x
Make into linear equation
y = 16x - 3 / 4x
Now, let's substitute the variables into the formula
Perimeter = 2 ()
Find the LCM of the bracket
Perimeter =
Perimeter =
2x = 4x² + 16x - 3
Collect like terms
4x² + 16x - 2x - 3 = 0
4x² + 14x - 3 = 0
Thus, the expression that represents the perimeter of the rectangle is 4x² + 14x - 3 = 0

Answer: B. 33%
Step-by-step explanation:
- In Mathematics , a percentage is basically a process of dividing the numerator by the denominator , then multiply the answer by 100.
We use Mathematical Formula :
Since , Difference between the Weight of 0.20 and Weight of 0.15 = 0.20-0.15=0.05
Then, substitute the value in formula , we get
Hence, the weight of 0.20 is 33% more important than a weight of 0.15.
Answer:
Step-by-step explanation:
The thing with the arc length formula, s = rt, is that t is the angle in radians. Ours is in degrees, so we have to change it:
36 ×
So the formula we use to solve for r is:
Multiply both sides by 5 over pi to get that
