Answer:
x = 12.
Step-by-step explanation:
If P(5,4),Q(8,10) and R(x,18) are collinear
then the slope of PQ equals the slope of QR
hence:
(10 - 4)/(8 - 5) = (18 - 10)/(x - 8)
6/3= 8/(x - 8)
2 = 8/(x - 8)
multiplying both sides by (x - 8) gives:
2(x - 8) = 8
2x - 16 = 8
2x = 8 + 16 = 24
hence x = 12
1 = x + 4
3 = x
2 = 2x + 5
3 = 2x
3/2= x

Answer:
4 1/2. Root 18 simplifies to 4.242640687, which is less than 4.50
No it is not greater than 5
When ever you are multiply a number by 1/2 you are halving the number. So in the us case 3 x 1/2 is 1.5.
And 1.5 is not greater than 5
So the answer is no
