Answer:
x = 6 and the +4x is wrong
Step-by-step explanation:
2x + 4x + 4 = 4(x + 4)
6x + 4 = 4x + 16
+4x +4x <--( <u>This part is wrong</u> )
10x + 4 = 16
-4 -4
10x = 12
10 10
x = 1.2
Correct steps
2x + 4x + 4 = 4(x + 4)
6x + 4 = 4x + 16
-4x -4x
2x + 4 = 16
-4 -4
2x = 12
2 2
x = 6
Step-by-step explanation:
First step:
Calculate a slope.
The formula of a slope:

The slope-intercept form of an equation of a line:

m - slope
b - y-intercept
We have the points (5, -4) and (-1, 8). Substitute:

Put the value of the slope and the coordinates of the point (5, -4) to the equation of a line:

<em>add 10 to both sides</em>

Finally:

Answer:
3√2
Step-by-step explanation:
If you draw the diagonal, you have a 45°45°90° triangle.
The two legs are 3, so the hypotenuse is 3√2
