X+x²=30
x²+x-30=0
(x+6)(x-5)=0
x=-6 or x=5
3a= 3(5) = 15
15 - - 3 = 15+3 = 18
18/6 = 3
b + a = 5 + -3 = -3 + 5 = 2
3 x 2 = 6
Answer:
4
Step-by-step explanation:
the figures are
0,0,3,8,1,0
we repeat 0
so we have 4 figures,
0,3,8,1
John exercised 20% more than Toby. So the number of hours that John exercises per week is 14 + 0.2(14) = 14 + 2.8 = 16.8.
Jenny exercises two more hours than John. So the number of hours that Jenny exercises per week is 16.8 + 2 = 18.8.
So an expression representing the number of hours that Jenny exercises after w weeks is 18.8w.
The cycle number two is the answer
