Answer:
11.9
Step-by-step explanation:
I just know this off the top of my head
The real one is 11.18034
Y is a vertical axis
x is a horizontal axis
when drawing a line, the line drawn to them is perpendicular so lines only touching the x axis are vertical and lines touching only the y axis are horizontal
the
a vertical line is x=value
the only thing that works is x=12
Hi there! :)

4x + 5x + 12 = 6(x - 2)
Combine like terms and distribute the coefficient outside of the parenthesis:
9x + 12 = 6(x) + 6(-2)
9x + 12 = 6x - 12
Subtract 6x from both sides:
9x - 6x + 12 = 6x - 6x - 12
3x + 12 = -12
Subtract 12 from both sides:
3x + 12 - 12 = -12 - 12
3x = -24
Divide both sides by 3:
3x/3 = -24/3
x = -8.
If the hypotenuse is 58cm, and one of the others legs is 42cm the answer would be 40cm
Explanation:
Here you have to use the formula

Then you have to pose the formula in terms of one of the legs, so:


So when you change the letter for numbers you have that:

a=40
