Lena found the greatest common factor (gcf) of 24ab2c3 and 30a2b3c2 to be 6abc2 by using these steps:
step 1: gcf of 24 and 30 is 6
step 2: highest shared power between a and a2 is a
step 3: highest shared power between b2 and b3 is b
step 4: highest shared power between c3 and c2 is c2
in which step did lena make a mistake?
a) step 1
b) step 2
c) step 3
d) step 4
e) lena's work is correct.

How do i do this? i don’t understand

Circle d circumscribes abc and abe. which statements about the triangles are true? statement i: the perpendicular bisectors of abc intersect at the same point as those of abe. statement ii: the distance from c to d is the same as the distance from d to e. statement iii: bisects cde. statement iv: the angle bisectors of abc intersect at the same point as those of abe. a. i only b. i and ii c. ii and iv d. i and iii e. iii and iv

Iwill give brainliest. suppose tommy walks from his home at (0, 0) to the mall at (0, 5), and then walks to a movie theater at (6, 5). after leaving the theater tommy walks to the store at (6, 0) before returning home. if each grid square represents one block, how many blocks does he walk?
