D = sq.root of((x2 - x1)^2 + (y2 - y1)^2)
sq.root of 13 = sq.root of((x - (-2))^2 + (1 - 3)^2)
= sq.root of((x + 2)^2 + (-2)^2)
= sq.root of (x^2 + 4x + 4 + 4)
= sq.root of (x^2 + 4x + 8)
Now if we square both sides:
x^2 + 4x + 8 = 13
x^2 + 4x - 5 = 0
(x + 5)(x - 1) = 0
x = -5 or x = 1
Step-by-step explanation:
0.0326 = 326/10000 = 163/5000
What are the following terms?
C. 21/45
If you multiply both the 7 and 15 by 3, you get 21 and 45.
Answer:
44 ft
Step-by-step explanation:
You would subtract 657 - 613
I think this is correct:
110 + 75 = 195
195 / 2 = 97.5
I am not fully sure about this, consult your teacher
