Answer:
The value of x is:

Step-by-step explanation:
we have to use the quadratic formula to solve for x.
The equation is given as:

which could also be written as:

The quadratic formula for the quadratic equation of the type:
is given as:

Here we have:
a=4, b=-5 and c=8.
Hence, by the quadratic formula we have:

Hence, the value of x is:

The equation in slope intercept form is:

A line parallel to this would have the same slope, which means our line that passes through the point (0,-4) has a slope of -3. We now have to plug in 0 as our x and -4 as our y in y=-3x+b so:

Our equation is then y=-3x-b
The surface area would be 166.
x/20 = 21/14 (similar proportions)
x/20 = 3/2 (simplify by canceling out a factor of 7)
x = 30
Answer:
I got -3+11x
Step-by-step explanation:
-3(1-3x)+2x
-3+9x+2x
-3+11x
