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:
96
Step-by-step explanation:
A quick but accurate way to approach this question would be to multiply 60 by 1.60. We get 1.60(60) = 96.
Note that 1(60) = 60, and that 0.60(60) = 36, and that 60 + 36 = 96. The earlier method is faster.
Answer:
1 1/8
Step-by-step explanation:
5/4 x 9/10 = 45/40
Simply 45/40 and you get 1 1/8
Hope this helps!
