Answer:
C) x = 20.8
Step-by-step explanation:
Since the line with the length equal to 6 forms a right angle on line x then we know it is perpendicular and bisects it.
Plug in the values: a^2 + b^2 = c^2
a^2 + 6^2 = 12^2
a^2 + 36 = 144
a^2 + 36 - 36 = 144 - 36
a^2 = 108
√a^2 = √108
a = √108
a = 10.3923048454
a = 1/2 x
2a = x
2(10.3923048454) = x
x = 20.7846096908
x = 20.8
Answer:
C
Step-by-step explanation:
C. x=7, y=5
That's false
-7+9=2
and 7+9=18
Answer:
63.7 feet
Step-by-step explanation:
We can re-write the width and the length both as rational numbers:
- Width: 
- Length: 
So now we can find the area of the garden by multiplying width and length:

Answer:
$5 bill
Step-by-step explanation:
If Rhonda has $13 and she has a $5 bill and 3 $1 bills, then she has
5 + 3(1) + x = 13
5 + 3 + x = 13
8 + x = 13
x = 5.
The last bill must be a $5 bill to equal the remaining $5.
