The differences between the two types of solving these equations is that when you solve with a CD that isn't the LCD, you must simplify the equation afterward. While sometimes you must do that while solving with LCD, you will always have to if you solve with any other CD. For example, adding 1/2 and 1/3 using the LCD (6) will get you 3/6 + 2/6 = 5/6. No simplifying. Using 12 as the CD, you get 6/12 + 4/12 = 10/12 which you have to simplify into 5/6.

Determine the smallest dimension to use
To answer this question, I'll make use of the attached figure as a point of reference.
The area of the printed matter is:
Substitute 150 for A1
Make H the subject
The area of the full paper is:
Substitute 150/W for H
Open brackets
Collect Like Terms
Differentiate with respect to w and set the result to 0
Set to 0
Collect Like Terms
Cross Multiply
Make the subject
Take positive square root of both sides
Recall that:
Hence, the smallest dimension of the paper is:
4*x = 4x 4*2=8
4x +8 + 2 = 14
8 + 2= 10
x=1
4x1=4+8+14
Answer:
f(6)
Step-by-step explanation:
f(t) represents the cost for t years after 2000. Then for 2006, t=6 and the cost is ...
f(6)
When the slope of a line is undefined, it means that the line is either vertical or horizontal. If the x intercept is -7, the equation would be
x = -7
