Answer:
28.9
Step-by-step explanation:
3+5(6.2)-(24-9(2.1))
3+31-(5.1)
34-5.1
28.9
Answer:
9.
Step-by-step explanation:
|2x+6|-4=20
or,|2x+6|=24
or,2x=24-6
or,x=18/2
x=9
multiples of 6 = 6, 12, 18, 24 , 30, 36 ,42 , 48
multiples of 8 = 8, 16, 24,32,40,48
24 & 48 are the common multiples
so there is a 2 out of 48 chance which is 2/48 which reduces to 1/24 probability
If you are working out the diagonal line you need to use Pythagoras Theroum: c² = a²+b²
c² = 7²+12² = 193
√c² = c = √193 = 13.89
The length of the diagonal side is 13.89,
Hope this helps! :)
