The unit for mass is grams, or g.
Hope this helps!
Length of the given rectangle is 8 units.
Option - D
<u>Solution:</u>
Given that
Length of a rectangle = 
Width of a rectangle = 
Area of rectangle = 20 square units
Need to calculate length of rectangle.
Substituting given value of Area of rectangle and expressions for length and width of rectangle in formula, we get
On solving above equation for x we get
On splitting the middle term in such a way that product of split terms comes as 
and summation comes as -5x, we get
As length cannot be negative hence we can ignore negative value.
So length is 8 units.
The x-coordinate of our midpoint = 3
The x-coordinate of Y = 0
k = x-coordinate of Z
3 = (0 + k) / 2
Multiply both sides by 2
6 = k + 0
Simplify
6 = k
The y-coordinate of our midpoint = 3
the y-coordinate of Y = 5
w = y-coordinate of Z
3 = (w + 5) / 2
Multiply both sides by 2
6 = w + 5
Subtract 5 from both sides
1 = w
For problem #17, Z(6, 1)
Let's do problem 18 now.
The x-coordinate of our midpoint = 5
The x-coordinate of Y = -1
k = x-coordinate of Z
5 = (k + (-1)) / 2
Multiply both sides by 2
10 = k + (-1)
Simplify the right side
10 = k - 1
Add 1 to both sides
11 = k
The y-coordinate of our midpoint = 9
The y-coordinate of Y = -3
w = y-coordinate of Z
9 = (w + (-3)) / 2
Multiply both sides by 2
18 = w + (-3)
Simplify the right side
18 = w - 3
Add 3 to both sides
21 = w
For problem #18, Z(11, 21)
Answer:
EF = 34.3
HD = 53.2
GE = 45.7
GOOD LUCK FOR THE FUTURE! :)
4 4/5 you make the whole number a fraction by putting a 1 under it and the multiply like normal then make it into a mixed number<span />
