Answer:
x = -2
Step-by-step explanation:
5x + 2(x - 4) = 5x + x - 10
First, we need to to multiply out the parathesis in the equation:
5x + 2(x - 4) = 5x + x - 10
5x + 2x - 8 = 5x + x - 10
Next, we can combine "like terms" to simplify the equation further:
5x + 2x - 8 = 5x + x - 10
7x - 8 = 6x - 10
Now we can isolate the variable "x" to one side:
7x - 8 = 6x - 10
x - 8 = -10
x = -2
To check our work, we can replace x with -2 in our original equation:
5x + 2(x - 4) = 5x + x - 10
5(-2) + 2 (-2 - 4) = 5(-2) + -2 - 10
-10 + 2 (-6) = -10 -2 - 10
-22 = -22
I hope this helps!

A miler is longer than a kilometer.

Area=LW
x^2-16=L(x+4)
remember difference of 2 perfect squares to factor x^2-16
(x-4)(x+4)=L(x+4)
divide both sides by (x+4)
x-4=L

Y = -18 x + 66.
Since the bathtub is draining at a constant rate, it can be modeled with equation y = mx + c ( m is the constant draining rate )
To find m, do 12 - 30 = 18
