Answer:
11.19ft * 15.19ft
Step-by-step explanation:
Width = x
Length = x-4
Area = 170ft2
Area of a rectangle = Length * Width
170ft^2 = (x-4) * x
x(x-4) = 170...........equation(1)
x^2-4x-170 = 0......equation(2)
Using the quadratic equation(for equation 2),
-b+-sqrtb^2-4ac/2a
from equation(2): a=1x=1
b= -4
c= -170
thus, x= 4 + sq.rt696/2 = 4 +26.38 =30.38/2=15.19
Answer:
x = 1
Step-by-step explanation:
When you subtract the smallest number from the biggest number, the answer is called the range. Here the largest number is 21. The smallest is 3. Then the range should be 18. But since it's 20. This mean that x is 1. Because 21 - 1 will equal 20, making 20 the range. So the correct answer is 1.
