2nd one is answer
Answer:
154
Step-by-step explanation:
The important thing to recognize about finding the area for these types of figures is to make it into shapes that are easier to calculate, such as rectangles.
1) There are different ways of creating rectangles from this figure; however I will choose to cut the shape into two rectangles:
Imagine if the "L" was cut down from the top part of the "L" to the bottom, as to create to rectangles.
There will be a tall vertical rectangle and a small horizontal rectangle.
The tall rectangle will have a length of 17 and a width of 6
The smaller rectangle will have a length of 4 and a width of 13
2) Calculate the areas of the two rectangles and add them together:
Tall: 17 * 6 = 102
Small: 4 * 13 = 52
Total = 102 + 52 = 154
Answer:
2x - y = -10
Step-by-step explanation:
Standard form: x + y = n
y - 4 = 2x + 6
y = 2x + 6 + 4
y = 2x + 10
2x - y = -10
Answer:
<h2>-6</h2>
Step-by-step explanation:
y= -6x+4 is in y=mx +b
Divide through both sides by 
:
Now let 
, so that 
. Then
Multiply both sides by 
:
Integrate both sides to get
Solve for 
:
Given that 
, we have
so the particular solution is
which we can rewrite as
