Answer:
10 and 6
Step-by-step explanation:
Let A be the area of the rectangle, w the width and L the length
● A = w*L
The length is 4 feet more that the width so L = w+4
● A = w ×(w+4)
● A = w^2 + 4w
The area is 60 ft^2
● w^2 + 4w = 60
Substract 60 from both sides
● w^2 + 4w - 60 = 0
This a quadratic equation
We will solve it by graphing it
The solution are 6 and -10 since the graph intersect with the x-axis in those points (pictures below)
The width is 6 feet long since it is a distance and a distance is always positive.
● w = 6
● L = w + 4
● L = 6 + 4
● L = 10
The width is 6 feet and the length is 10 feet

Answer:
b = 20x beads
Step-by-step explanation:
In this question, we will be trying to relate the number of beads to the number of bracelets.
From the question, we can identify that each of the bracelets will have 20 beads. The total number of bracelets to be made is x. This means that the total number of beads to be used can be calculated by multiplying 20 by x = 20x beads. This number is same as b, which is equal to the total number of beads.
Hence, we can say that b = 20x beads
