The answer is: " -3x² + 6 " .
_________________________________________________
Explanation:
_________________________________________________
(2x² + 3x - 4) + (8 - 3x) + (- 5x² + 2) =
2x² + 3x - 4 + 8 - 3x + 1(- 5x² + 2) ;
_____________________________
Note: 1(-5x² + 2) = - 5x² + 2 ;
______________________________
2x² + 3x - 4 + 8 - 3x + 1(- 5x² + 2) =
2x² + 3x - 4 + 8 - 3x - 5x² + 2 = ?
_____________________________
Combine the "like terms" ;
+2x² - 5x² = - 3x² ;
+3x -3x = 0
-4 + 8 + 2 = 6 ;
___________________________________________________
So, we have: " - 3x² + 6 " .

Answer:
measure of angle K is 48° or m∠K = 48°
Step-by-step explanation:
Given:
ΔJKL= ΔPQR
m∠P = 52°
m∠Q = 48°
m∠R = 80°
When 2 triangles are equal or congruent to each other then their corresponding angles are equal or congruent by congruence property.
Hence ,
m∠P = m∠J
m∠Q = m∠K
m∠R = m∠L
But m∠Q = 48° hence m∠K = 48°
Hence measure of angle K is 48°

Answer:
k = 15
Step-by-step explanation:
k² = 225
k = √225
k = 15
Thus, K = 15
