Answer:
<h2>D) (12 × 8) + (12 × 5)</h2>
Step-by-step explanation:
The distributive property: <em>a(b + c) = ab + ac</em>
<em></em>
We have 12(8 + 5).
Use the distributive property:
12(8 + 5) = (12)(8) + (12)(5) = (12 × 8) + (12 × 5)

Answer:
Step-by-step explanation:
Given is a function f(x)
![f(x) = e^x -e^{-\frac{{x}}{2}](https://tex.z-dn.net/?f=f%28x%29%20%3D%20e%5Ex%20-e%5E%7B-%5Cfrac%7B%7Bx%7D%7D%7B2%7D)
We have to analyse and sketch the graph
X intercept : Put y =0, we get x=0
Y intercept: Put x =0 , we get y =0
No exception for x or y and hence set of all real numbers is domain and range.
![f'(x) = (e^x +1/2 e^{-\frac{{x}}{2})](https://tex.z-dn.net/?f=f%27%28x%29%20%3D%20%28e%5Ex%20%2B1%2F2%20e%5E%7B-%5Cfrac%7B%7Bx%7D%7D%7B2%7D%29)
f' becomes 0 not at finite points
So relative extreme
Graph is sketched and attached

D has the rate of change of 20
Answer: D) 10
============================================================
Explanation:
I'm assuming points M and N are midpoints of segments FD and FE respectively. If that's the case, then segment DE is twice as long compared to segment MN. We consider MN to be a midsegment.
So,
DE = 2*(MN)
3x-2 = 2*(x+4)
3x-2 = 2x+8
3x-2x = 8+2
x = 10
