8. Factorisc cach of the following: (1) 8a+ b3 +12ab + bab?
(iii) 27 -125a - 135a +225a2
(ii) 8a - 63 - 12a²b +6gb
(iv) 6403-27b3 - 17ab+108 a b square

about 168 miles

step-by-step explanation:

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92

you would need to also lose 1 point for each of the other outcomes for it to be fair.
