ethan runs for exercise during the week. on the weekends he runs 10 more blocks than he does during the week. ethan represented the number of blocks he runs on weekends using the expression m + 10.

which expression represents the total number of blocks ethan ran one weekend if he ran 12 more blocks than his usual number?

a m + 12

b 10 + 12

c m + 10

d m + 22

plz

I've been working on this for a few days and i just don't understand, it's due in a few hours. you. the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α. part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part b suppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i.e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case. part c now try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
