Answer:
18) it is parallel to y axis
We divide 72/96 which the answer is 0.75 or 75%
Answer:
a) 675 000
b) 685 000
Step-by-step explanation:
The population of a town is 680 000 correct to the nearest 10 000.
a) To find it lower bound, we level of accuracy by 2 and then subtract from 680 000
The lower bound is:
680 000-5000=675,000
Therefore the least possible population of the town is 675 000
b) We repeat the same process to find the upper bound
680 000+5000=685,000
Division of a fraction is the equivalent of multiplying by its reciprocal

i suggest you try to remember this concept
in terms of your question
from this point, just multiple the numerators together and denominators together, then simplify if necessary
fyi- difference of squares

relating that to

also a side note, you might want to factor out the 4 first in the top fraction
