<u>Answer:</u>
x = -3/7
<u>Step-by-step explanation:</u>
We are given the following equation for which we have to solve for x:
So we will start by expanding the equation by multiplying the common factor with the brackets to get:
Arranging the like terms together (variables on one side of the equation and constants on the other side) to get:
Therefore, x = -3/7.
Answer:
c(h) = 40*h + 50
Step-by-step explanation:
Let h be the variable that represents the number of hours
As the cable operator charges $40.00 for an hour so for h hours, the expression will be 40*h
And
Lastly, he has to charge $50.00 must as service charge,
As the number of hours is variable here so the function will be in terms of hours.
So the resulting function will be:
c(h) = 40*h + 50

Step-by-step explanation:
Because its the retail price.
Given:
area of square, A = 16 
error in area, dA = 0.03 cm^{2}
Step-by-Step Explanation:
Let 'a' be the side of the square
area of square, A = 
(1)
A = 16 =
Therefore, a = 4 cm
for max tolerable error in length 'da', differentiate eqn (1) w.r.t 'a':
dA = 2a da
da = 
da = 0.0375 cm
