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
The Answer is: B 8x^2 + 34; 45.52 centimeters
Took it on edg
900,008,007
first add 90000,1000 +7000=900,008,000
then add 7 with 900,008,000
Answer =900,008,007
