Answer:
14
Step-by-step explanation:
you can simplify it by turning a²+b²/a-b
into
(a-b)²+2ab / a-b
eliminate the fraction
a-b +2ab
a=-1
b=-5
-1-(-5)+2*-1*-5
-1+5+10 = 14
Answer:
324?
Step-by-step explanation:
A) The experimental probability is 1/1 = 1
b) The experimental probability is 2/6 = 1/3
c) The experimental probability is 4/12 = 1/3
d) The theoretical probability is 1/6
Step-by-step explanation:
let no. of hours be x.
45x - 12 ≥ 117
45x ≥ 129
x ≥ 2.8667 (5sf)
therefore, 3 hours (round up to next whole number).
