Step-by-step explanation:
1
(x + 5)² = 4 ( take the square root of both sides )
x + 5 = ± = ± 2 ( subtract 5 from both sides )
x = - 5 ± 2, thus
x = - 5 - 2 = - 7
x = - 5 + 2 = - 3
--------------------------------------------
2
(x + 6)² = 7 ( take the square root of both sides )
x + 6 = ± ( subtract 6 from both sides )
x = - 6 ± , thus
x = - 6 -
x = - 6 +
------------------------------------------------
3
(x - 2)² = 18 ( take the square root of both sides )
x - 2 = ± = ± = ± 3 ( add 2 to both sides )
x = 2 ± 3, thus
x = 2 - 3
x = 2 + 3
Answer:
Where is the graph.
Step-by-step explanation:
Where is the graph.
The order of the numbers from the greatest to the least is
|-20| > |12.3| > |8| > |-6| > |-4| > |2 3/10|
<h3>Magnitude of numbers</h3>
From the question, we are to order the given numbers from the greatest to the least in magnitude
The given numbers are
|-20|, |-4|, |-6|, |8|, |2 3/10|, |12.3|
Since the modulo sign is included, the <u>negative signs</u> do not take effect.
Hence, the order of the numbers from the greatest to the least is
|-20| > |12.3| > |8| > |-6| > |-4| > |2 3/10|
