Answer:
0
Step-by-step explanation:
20 feet, 12+12+L+L=64 so you simplify and it becomes 24+L+L=64. Take away 24 from 64 and you get 40. 40 divided by 2 equals 20, and you can plug 20 into the L spots and it all works.
Answer
x =
1/√3 and
x =
-1/√3 or in decimals x = + 0.577350269 and
= - 0.577350269
Explanation
-3(3x)² + 3 = -6
-3×9x² + 3 = -6
-27x² = -6-3
-27x² = -9
x² =-9/(-27)
= 9/27
x = +√(9/27)
x = 3/√27
= 3/√9×3
= 3/3√3
= 1/√3
or in decimals x = 0.577350269
Also x = -√(9/27)
x = +√(9/27)
x = -3/√27
= -3/√9×3
= -3/3√3
= -1/√3
or in decimals x = -0.577350269
Answer:
b and e
Step-by-step explanation:
Number of days = x
Amount of soda = y
An equation that can represent the relationship between amount of soda and number of days can be represented in the form of y = mx
Where slope (m) = y/x
Using any point on the line, say (1, 40),
m = 40/1
m = 40
Plug the value of m into y = mx
Thus, we have:
y = 40x
This can also be rewritten as:
y/x = 40
Therefore, the equations that can be used to represent the relationship are:
y = 40x or y/x = 40
