Answer:
Step-by-step explanation:
let the 3rd side, the hypotenuse, be x
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² = 2² + 3² = 4 + 9 = 13 ( take square root of both sides )
x =
Answer:
a = 15
Step-by-step explanation:
Substitute b = 12 , a = 9 into the equation
12 =
12 = ← square both sides
144 = a² - 81 ( add 81 to both sides )
225 = a² ( take square root of both sides )
± = a , then
a = ± 15
a > 0 , so a = 15
Answer:
9 should be added to both sides of the equation to complete the square.
Step-by-step explanation:
Given :
To Find: What number should be added to both sides of the equation to complete the square?
Solution:
Add the square of half of coefficient of x
So, the square of half of coefficient of x =
So,
Thus 9 should be added to both sides of the equation to complete the square.
