X = (12 +- sqrt (144 -4(7)(3))/14
x = (12 + - sqrt (144 - 84))/14
x = (12 + - sqrt(60))/14
x = (12 + - 2sqrt 15))/14
x = (6 + - sqrt 15) / 7
Yes it is a 90 degree rotation clockwise.
OK so the factor of 10 is 1 times 10 and 5 times 2
Answer:
900
Step-by-step explanation:
Might wanna double check. I rushed
(7m-2m^2n)^2
-42+144
