X÷4+9=12 plzzzzzzzzzzzzzzz help step by step
xeze [42]
So we are trying to solve for x so in order to do that we need to get x by itself on one side of the equal sign

first we are going to combine like terms on each side of the equal side

so on the left side we see 4+9 these are booth whole numbers not attached to a variable so we can simplify this by adding these two values together making our equation: x/13 = 12

our x is still not by itself so in order to get it by itself we need to get rid of that 13

we need that x is being divided by 13 so in order to get rid a divided value we have to do the opposite to both sides - multiply by 13 on each side!

x/13 x 13 = x
12 x 13 = 156

so our equation is now:
x = 156

is our x by itself on one side of the equal sign? yes! so our x value is 156

Find the missing side of each triangle. Leave your answers in simplest radical form.
jeka57 [31]

Answer:

x = 2\sqrt{34}

Step-by-step explanation:

Using Pythagoras identity in the right triangle

x² = 10² + 6² = 100 + 36 = 136 ( take the square root of both sides )

x = \sqrt{136} = \sqrt{4(34)} = 2\sqrt{34}
