What is x? and if you can't see y, it's 18

Step-by-step explanation:

The image is attached below.

Given AB = 9

BC = x

AC = y = 18

Note that the given triangle is a right angled triangle.

We know that Pythagoras theorem states that in a right angle hypotenuse is equal to the sum of the squares of other two sides.

Using Pythagoras thereom,

Taking square root on both sides,

Hence, the value of x is .

its d. the first coordintaes are 10,32

step-by-step explanation:

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5
