How much bigger is B than A , so Side length B- A = (-4x+18) - (2x-7) = -6x+25
So perimeter = 4x length = 4x(-6x+25) = -24x+100 = 100-24x
How much bigger? 100-24X

Step-by-step explanation:
Answer:
a
Step-by-step explanation:
Answer:
The temperature at the start is 35F
The temperature of the room is 74F
<em></em>
Step-by-step explanation:
Given

Solving (a): The temperature at the start.
To do this, we set: 
So, we have:




<em>Hence, the temperature at the start is 35F</em>
<em></em>
Solving (b): The room temperature
We have:

To get the temperature of the room, we simply remove the exponential function.
So, we have:

<em>Hence, the temperature of the room is 74F</em>
