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:
n ≤ 3 67/80
Step-by-step explanation:
The symbolic inequality here is 6n - 4 9/10 ≤ 18 1/8.
or 6n - 4.9 ≤ 18.125.
Adding 4.9 to both sides, we get 6n ≤ 23.025, or n ≤ 3.8375, or
n ≤ 3 67/80
