B. You can determine this by remember that the ordered pair is like a coordinate, the first digit represents the x and the second represents the y. Plug them in to both equations and if they work in both then it’s a solution, if it works in only one it is not.
Answer:
The answer to your question is Perimeter = [4x³ + 14x² + 50x - 150] / x(5 + x)
Step-by-step explanation:
Data
Width = (x² + 2x - 15)/x
Length = (3x² + 4x)/ (5 + x)
Process
1.- Write the formula for the perimeter of a rectangle
Perimeter = 2W + 2L
2.- Substitution
Perimeter = 2(x² + 2x - 15)/x + 2(3x² + 4x)/(5 + x)
3.- Simplification
Perimeter = (2x² + 4x - 30)/x + (6x² + 8x)/(5 + x)
4.- Sum the fractions
Least common factor = x(5 + x)
Perimeter = [(2x² + 4x - 30)(5 + x) + (x(6x² + 8x)] / x(5 + x)
-Simplification
Perimeter = [10x² + 20x - 150 - 2x³ - 4x² + 30x + 6x³ + 8x²] / x(5 + x)
Perimeter = [4x³ + 14x² + 50x - 150] / x(5 + x)
Answer:
5.57 feet
Step-by-step explanation:
In this problem, the light string, the height of the mast and the distance between the base of the mast and the end of the string form a right triangle, in which:
- The hypothenuse is the string
- The height is the mast
- The base is the distance between the base of the mast and the end of the light string
Here in this problem, we have:
(length of the string, hypothenuse)
(height of the mast, height)
So we can find the distance between the base of the mast and the end of the string just by applying Pythagorean's theorem:
