A) work out (5 x 10°) * (9 x 10')
give your answer in standard form.
b) work out (7 * 10%) = (2 x 10)
give your answer in standard form.

A) 4,500

B) 1,400

Step-by-step explanation:

those are the answers because 50*90  is 45 plus the two zeros then 70*20 is 14 plus two zeros.

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
