6.5 is the answer for that problem
Answer:
From the information given
x is time for which she ran at speed of 6mi/h and
y is time for which she biked at speed of 12.5 mi/h
total time = 3.5 h
total distance = 34 mi
so
6x + 12.5y = 34 and
x + y = 3.5
x = 3.5 - y
6 ( 3.5 - y) + y = 34
6.5y = 13 which gives
y = 2 and this
x = 1.5
so suze ran for 1.5 h and biked for 2 h
CHECK
speed of run X time of run + speed of biking x time of biking must be = total distance covered
6 × 1.5 + 12.5 × 2 = 9 + 25= 34 mi
which is true

The answer to your question is Width = 
Step-by-step explanation:
Data
Area = (x² - 4)/2 x in²
Length = (x + 2)² / 2 in
Width = ?
Process
1.- Write the formula of the area of a rectangle
Area = length x width
-Solve for width
Width = Area / length
2.- Substitute the values
Width = (x² - 4)/2 / (x + 2)² / 2
-Simplify
Width = (x² - 4) / (x + 2)²
-Factor both numerator and denominator
Width = (x - 2)(x + 2) / (x + 2)(x + 2)
- Simplify
Width = (x - 2) /(x + 2) or Width =
The volume of a box is the length x with x height. Because it is a cube all the sides are the same size, and it’s has three dimensions. That means you can calculate the length of one side by picking the root^3 (I don’t know what it is in English it is a square root with a 3 in the upper left corner) of 512. That gives you 8, so the sides are 8 inches Kong’s
