First replace the letters with the numbers it gave so you have 3(2)(7)^2-(2)^2
multiply the 3 and 2 together to make 6(7)^2-(2)^2
do seven to the second power (7x7) so you get 6(49)-(2)^2
-(2)^2 is the same as -1(2)^2, so that can just become -2^2. so you now have 6(49)-2^2
multiply 6x49 so you have 294-2^2
do two to the second power (2x2) so you get 294-4
294-4=290
Answer:
( -
/2 , -1/2)
Step-by-step explanation:
-210 degrees in standard position corresponds to an angle in the 3rd quadrant 30 degrees below the negative x-axis
The hypotenuse of the triangle here is 1, and we want the coordinates.

14 miles.....16hours
xmiles.......1hour
14x1=14
14/16=0,88 miles
Answer:
A' (11, 4), B' (-10, -6), C' (7, -9)
Step-by-step explanation:
Since you are reflecting over the y-axis, you take the opposite of the x value. So if the x is positive, make it negative. If the x is negative, make it positive. The y coordinate stays the same.
