Use distance formula: d = sqrt((x2 - x1)^2 + (y2 - y1)^2)
(11,-4) is (x1,y1) and (-12,-4) is (x2,y2)
Plug in and simplify
d = sqrt((-12 - 11)^2 + (-4 - -4)^2)
d = sqrt((-23)^2 + (0)^2)
d = sqrt(529 + 0)
d = sqrt(529)
d = 23 (positive because length cannot be negative)
Answer:
just remove the bracket and write normally so it's 23x+4-5b
Step-by-step explanation:
if you meant something else then let me know
Answer:
45
Step-by-step explanation:
45+6=51
51-6=45
Another method:
6-6=0
45+0=45
and so the aliens will need 56 power pouches for each day of the trip.
10. Answer is 9 . (51 - 6) / ( 3.5+5.5)
11. 5x-18 - 4x = -36
x -18 = -36
x = -18
Answer is -18
