Answer:
I got the one above it: L=-w
Step-by-step explanation:
To solve "P= 2(L+W)" , first distribute:
P= 2L+2W
Then get "2L" alone (by subtracting 2W from both sides):
P-2W= 2L-------- 2L= P-2W
Then divide by two to get just "L":
L= -W
Hope this helps!

Answer:
51.8
Step-by-step explanation:
10¹ = 10
5.18 × 10 = 51.8
multiplying by 10 moves the decimal point once to the right
Answer:
Linear function that models the volume of hydrogen in the balloon after t seconds is V(t) = 5 + 0.1t
Step-by-step explanation:
Initial volume of hydrogen in the balloon = 5 ft³
Rate at which hydrogen is filling in the balloon = 0.1 ft³/s
Volume after 1 second = 5 + 0.1 x 1
Volume after 2 seconds = 5 + 0.1 x 2
Volume after 3 seconds = 5 + 0.1 x 3
Volume after 4 seconds = 5 + 0.1 x 4
Volume after 5 seconds = 5 + 0.1 x 5
Similarly
Volume after t seconds, V(t) = 5 + 0.1 x t = 5 + 0.1t
Linear function that models the volume of hydrogen in the balloon after t seconds is V(t) = 5 + 0.1t
