Answer for #5
Two Points M(-7,1) and N(5,1).
1. Formula is
2. Let’s say (x1,y1) = (-7,1) and (x2,y2) =(5,1)
3. Distance =
so distance between two warehouses is 12 miles
Answer #6
In the question it is saying the “Distance between two stores is half the distance between warehouses“ so it is = 6 miles
Answer #7
S1(-4,1) and distance of S1 and M is 3 Miles.
Answer #8
S2(2,1) and distance of S2 and M is 3 miles.
Answer:
×
=
Step-by-step explanation:
×
To solve the above, we need to follow the steps below;
4k+2 can be factorize, so that;
4k +2 = 2 (2k + 1)
k² - 4 can also be be expanded, so that;
k² - 4 = (k-2)(k+2)
Lets replace 4k +2 by 2 (2k + 1)
and
k² - 4 by (k-2)(k+2) in the expression given
×
×
(2k+1) at the numerator will cancel-out (2k+1) at the denominator, also (k-2) at the numerator will cancel-out (k-2) at the denominator,
So our expression becomes;
Therefore, ×
