Answer:
8x^2 + 34; 45.52 centimeters
Step-by-step explanation:
The perimeter is twice the sum of adjacent edges of a rectangle:
P = 2((2x^2 +9) +(2x^2 +8)) = 2(4x^2 +17)
P = 8x^2 +34
Then when x=1.2, the perimeter is ...
P = 8(1.2^2) +34 = 8·1.44 +34 = 45.52 . . . . cm
Answer:
x = 7
Step-by-step explanation:
2(3x - 8) = 26
First distribute the left side:
6x - 16 = 26
Add 16 to both sides
6x = 42
Divide both sides by 6
x = 7
The answer would be 18 since you multiply 108 by 2 and divide by 12.
Answer:
1 : 3
Step-by-step explanation:
Given the following :
First day :
Patient received = 24
Patient discharged = 6
Second day :
Patient received = 8
Patient discharged = 21
First day :
Patient received = 9
Patient discharged = 6
Number of patient in the hospital at the end of the third day:
Patients received = (24 + 8 + 9) = 41
Patients discharged = (6 + 21 + 6) = 33
Patient received - patient discharged
= (41 - 33) = 8
Number of patients in hospital at the start of the three day period :
Patient received on first day = 24
Patient at the end : patient at the start
8 : 24 = 1 : 3
