Answer:
x=34
Step-by-step explanation:
x+(x+12)+(100) = 180
2x+112=180
x=68
x=34
Answer:
x= -8 , x=5
Step-by-step explanation:
2x^2+6x-80=0
x^2+3x-40=0
look for 2 numbers that their:
sum = 3
product = -40
(x+8)(x-5)=0
thus
x= -8 , x=5 (ANS)
Answer:
-3x³ - 4x² + x - 9
Step-by-step explanation:
-5x³ + 2x² + x - 7
- <u>(-2x³ + 6x² + 0 + 2)</u> remember: when you subtract, you 'add the opposite'
-3x³ + (-4x²) + x + (-9)
The answer is x=-9
Hope this helped:)
Based on the hints of distinguishing between <em>radical</em> and <em>non-radical</em> numbers, we have the following lists:
,
, 2.5, 
- 3.01,
,
, 
, - 4.1, 4.01, 
- - 2.5,
,
, 2.5
<h3>How to order numbers from least to greatest</h3>
In this question we must order sets of numbers in ascending order. A hint consists in comparing <em>non-radical</em> numbers with the <em>closest</em> <em>radical</em> numbers whose results are integers.
In consequence, we obtain the following orders:
,
, 2.5, 
- 3.01,
,
, 
, - 4.1, 4.01, 
- - 2.5,
,
, 2.5
