What’s the question ???????
(ab+3)(ab−3)
=(ab+3)(ab+−3)
=(ab)(ab)+(ab)(−3)+(3)(ab)+(3)(−3)
=a^2b^2−3ab+3ab−9
=a^2b^2−9
Irfan must walk a distance of <u>25</u> blocks <u>east</u> to return to his apartment building.
<h3>What is a compass?</h3>
A compass can be defined as a scientific instrument that contains a magnetized pointer, which is used to show and indicate the following four (4) main cardinal directions:
<h3>What is distance?</h3>
Distance can be defined as the amount of ground covered (traveled) by a physical object over a specific period of time and speed, regardless of its direction, starting point or ending point.
Next, we would calculate the total distance covered (traveled) by Irfan as follows:
Total distance = 20 + 5
Total distance = 25 blocks.
Since Irfan walked a total distance of 25 blocks west, he would have to walk the same distance in the opposite direction (east) to return to his apartment building.

Two numbers that multiply to -2 could be
-1 and 2
Or
-2 and 1.
Since -1+2=1, -1 and 2 are the numbers you are looking for.
Hope this helps!
