Answer:
t is between 0.47 seconds and 4.02 seconds
Step-by-step explanation:
Given

Required
Determine the values of t

Subtract 10 from both sides


Multiply through y -1

Solve t using quadratic formula:

Where



So, we have:




Split the equation
or 
or 
or 
or 
Hence; the range is

It depends on how many numbers there are.
Okay, one, how many pieces are in each package, and two, how many pieces does each person need?
Ok, so
Length = L
Width = L + 7
Since area = length x width, then
30 = L × (L + 7)
Remember that L + 7 Is width so...
L + 7 = 30/L
So the expression for the width in terms of length would be...
w = 30/L - 7
Answer:
x < -2.5 and x > 1
