Marked brainliest if correct. michael is 3 times as old as brandon. 18 years ago, michael was 9 times as old as brandon. how old is michael now?

Michael is 72.

hope this helps

Step-by-step explanation:

Let Brandon be b. Then Michael is 3g.

3g-18=9(b-18)

3g-18=9g-162

6g=144

b=24

3g=72

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

i believe the answer is 68cm

step-by-step explanation:

i just took 34 x 2 because the space between v and y is the same as y to k.
