Answer:
x = 5
Step-by-step explanation:
Applying Pythagoras' identity to the right triangle
x² + 12² = 13²
x² + 144 = 169 ( subtract 144 from both sides )
x² = 25 ( take the square root of both sides )
x = 
= 5

Step-by-step explanation:
Answer:
x=4 or x= - 16
Step-by-step explanation:
|x+6|
Now subtract 7 which equals to 3.
|x+6|-7=3
|x+6|=10
Now remove the mode by adding plus minus sign in the front of 10.
x+6=±10
x+6=10 or x+6=-10
x=4 or x=-16
Given equation :
2/3 y + 15 = 9.
We need to subtract 15 from both sides first.
<h3>2/3 y + 15-15 = 9 -15 <em>Subtraction property of equality.</em></h3>
Now, we need to simplify it.
We get
<h3>2/3 y = - 6 <em> simplification </em></h3>
Now, we need to get rid 2/3 from left side.
On multiplying both sides by 3/2,
<h3>2/3 y * 3/2 = - 6 * 3/2 <em>Multiplication property of equality.</em></h3>
On simplifying, we get
<h3>y = -9 <em>simplification </em></h3>
1/2 (One and a half) since 12 and 12 are even and there would be a fifty fifty chance of getting one or the other or two of the same.
