Answer:
5x^3
Step-by-step explanation:
its the 4th
Answer:
20
Step-by-step explanation:
Let A, B, C and D sets.
Let |A| the number of elements of A.
Remember, the quantity of elements that have the set is
1. Since each set has 100 elements,
2. each pair of the sets shares 50 elements
3. each three of the sets share 25 elements,
4. the four sets share 5 elements
Then
So, there are 20 elements in the union of the sets A, B, C and D
Parallel means it has the same slope.
Slope in thisproblem is -5/4.
This means the slope of the parallel line is also -5/4.
Perpendicular is the reciprical of the slope.
Flip the slope and make it +/-.
The slope would be 4/5.
The length of the field is 48 yard while the width of the field is 16 yards.
My Work/Reasoning:
Say that the width is "x" yards.
The length of the field is three times longer than the width.
The perimeter of the rectangle is 128 yards.
To get the perimeter of a rectangle you multiply the sum of the length and the width by two.
Then you follow order of operations and add x and 3x.
Then you multiply.
After that, you divide 8 on both sides to get the width (total) in yards.
Then you divide that to get the width.
Finally, to get the length of the field, you multiply the width of the field by three to get its length.
Answer:
x = -3
Step-by-step explanation:
The line parallel to x=8 is another vertical line:
x = constant
To make it go through a point with an x-coordinate of -3, the constant must be -3.
Your line is ...
x = -3
