Answer:
24x
Step-by-step explanation:
The total length of all vertical segments is 5x·2 = 10x.
The total length of all horizontal segments is (3x+4x)·2 = 14x.
Then the total length of all perimeter segments is ...
10x +14x = 24x . . . . perimeter of the figure

Answer:
At the 3rd day 160 students caught flu.
Step-by-step explanation:
Consider the provided model P = − t ² + 13t + 130 where 1 ≤ t ≤ 6
The total number of students is represents by P.
We need to find the day that 160 students had the flu.
Substitute the value of P=160 in above formula.






Hence the value of t=10 or t=3
But it is given that 1 ≤ t ≤ 6, Therefore select t=3
Hence, at the 3rd day 160 students caught flu.
Step-by-step explanation:
Distance between 2 towns 360 miles showed length 3 inches
1800 miles = ? inches
360 miles = 3 inches
1 miles = 3/360 inches
1800 miles = 3/360 × 1800
= 15 inches
