Answer:
Quadratic trinomial
Step-by-step explanation:
(8x^2 + 3x) - (12x^2 - 1)
= 8x^2 + 3x - 12x^2 + 1
= 8x^2 - 12x^2 + 3x + 1
= -4x^2 + 3x + 1
^ ^ ^
1 2 3
So the answer is Quadratic trinomial
Answer:
V = 0.512 m3
Step-by-step explanation:

Answer:
3.25×10^15
Step-by-step explanation:
(8.69×10)^8_(9.6×10)^6. (3.25)×10^15_(7.83)×10^11=3.25×10^15
Let's test each alternative :
2 x - 9 y = 38 ( 7,5 ) :
( 2 * 7 ) - ( 9 * 5 ) = 38
14 - 45 = 38
-31 ≠ 38 ( wrong )
( 4 , - 1 ) :
( 2 * 4 ) - ( 9 * ( - 1 ) = 38
8 + 9 = 38
17 ≠ 38 ( wrong )
( 3 , - 3 ) :
2 * ( 3 ) - ( 9 * ( - 3 ) = 38
6 + 27 = 38
33 ≠ 38 ( wrong )
( 1 , - 4 ) :
2* ( 1 ) - 9 * ( - 4 ) = 38
2 + 36 = 38
38 = 38 ( Correct alternative )
( 1 , - 4 ) is correct alternative
