Answer:
X = -20
Step-by-step explanation:
X = -2(6+4)
^ add 6 and 4 together first because they are in parentheses
-2(10)
^ this parenthesis means you want to multiply -2 and 10
because 2 x 10 = 20
that must mean -2 x 10 = -20
therefore, the value of X is -20
X= -20
Answer:
Step-by-step explanation:
Given
x - 
= 9 ← square both sides
(x - )² = 9²
x² - 2 + 
= 81 ( add 2 to both sides )
x² + = 83
Now
(x + )² = x² + + 2, thus
x² + = 83 + 2 = 85
(x + )²= 85 ( take the square root of both sides)
x + =
