X+8/4-x+5/4
The first term in the series is a positive "x", and the third one is a "-x". Since these are opposites, they cancel out
x+8/4-x+5/4
8/4+5/4
13/4
4 1/4
The answer is 42 cause you do ( 18*28=12x) wich is 504=12x which equals 42

Step-by-step explanation:
The rate of change in temperature is −17°F/min
<h3>Rate of change of a function</h3>
The formula for calculating the rate of change of a function is expressed as:
Rate of change = rise/run
This is also known as the slope of the function
Given the following parameters
Temperature = −25.5°F
Cooling time = 1.5mins
Determine the rate of change
Rate = −25.5°F/1.5min
Rate = −17°F/min
Hence the rate of change in temperature is −17°F/min
