Answer:
Step-by-step explanation:
Quadratic formula: when the equation is
The given equation is . Let's first arrange this so its format looks like :
Subtract 1 from both sides of the equation
Now, we can easily identify 3 as a, -2 as b and 0 as c. Plug these into the quadratic formula:
I hope this helps!
C because there is 180 degrees in a triangle. 147+17=164 and 180-164 is 16
Answer: Option C.
Step-by-step explanation:
You need to find the distance AB with the formula for calculate the distance between two points:
Then, substituting the coordinates of the points A(1,1) and B(4,1), you get:
You know that A'B'=6, then the scale factor of dilation can be calculated with:
Substituting values, you get:
This matches with the option C.
