a^2 and b^2 are 2 perfect squares and a^2 - b^2 are their difference.
2. The order of multiplication does not matter because in algebra multiplication is commutative ( meaning any order gives the same result).
Answer:
10 cm ....
Step-by-step explanation:
I'm not sure..
When given two points, use point-slope form

-5x -3x + 7x
-8x + 7x
-x
Thus, second option is correct.
Step-by-step explanation:
6m-1+73=180 (linear pair)
6m+72=180
6m=180-72
6m=108
m=108/6
m=18°
