Answer:
He has 7
Step-by-step explanation:
5 plus 2 equals 7
X-9 = -5x+ 9
x + 5x = 9 + 9
6x = 18
x = 3
Answer:
137°
Explanation:
In any triangle, the measure of the exterior angle is equal to the summation of the measures of the other two non-adjacent angles.
In the given triangle:
Angle 1 is an exterior angle.
The measures of the non-adjacent angles are 103° and 34°
Based on the above theorem:
measure angle 1 = 103 + 34 = 137°
Hope this helps :)
Answer:
see explanation
Step-by-step explanation:
1
Given
2x² - 16 = 0 ( add 16 to both sides )
2x² = 16 ( divide both sides by 2 )
x² = 8 ( take the square root of both sides )
x = ±
= ± 2
------------------------------------
2
Given
- 5x² + 9 = 0 ( subtract 9 from both sides )
- 5x² = - 9 ( divide both sides by - 5 )
x² =
( take the square root of both sides )
x = ±
= ± 
-----------------------------------------
3
Given
6x² - 15 = 27 ( add 15 to both sides )
6x² = 42 ( divide both sides by 6 )
x² = 7 ( take the square root of both sides )
x = ±
