Answer:
18x = 30x
i think thats it
Step-by-step explanation:
To solve this problem, the first thing you should keep in mind is the following conversion:
1 foot = 12 inches.
Therefore doing the conversion:
(12 inch) * (1 foot / 12 inch) = 1 foot.
The number of sections is:
N = (9 feet) / (1 foot) = 9
Answer:
you can get out 9, 12 inch sections of 9 foot calculator

Answer:
see explanation
Step-by-step explanation:
(a)
given 
+ 2 = 10 ( subtract 2 from each side )
= 8 ( square both sides )
2x - 6 = 64 ( add 6 to both sides )
2x = 70 ( divide both sides by 2 )
x = 35
As a check
+ 2 = 
+ 2 = 8 + 2 = 10 correct
(b)
given T= 8, then substitution into the formula gives
8 = 1.25
( divide both sides by 1.25
= 6.4 ( square both sides )
l = 6.4² = 40.96 feet
(c)
note that (g - f)(x) = g(x) - f(x), hence
x - 10 -(4x + 4) = x - 10 - 4x - 4 = - 3x - 14
