Answer:
(3a³-5b³)+ (-2)a³ +6b³=(a³+b³)
Step-by-step explanation:
First, lets remove the brackets. There is no "-" before the brackets, so we can just remove them at all.
3a³-5b³+ ...a³ +...b³=a³+b³
Now we can joint similar monoms (with variable a) ( and with variable b) in the left side of equation
3a³+...a³ -5b³ +...b³=a³+b³
Now we can notice that 3a³+...a³=a³ (1) and
-5b³ +...b³=b³ (2)
Lets find deduct 3a³ from both sides of (1)
...a³= a³-3a³
...a³= -2a³ So instead ... we have to type -2 (-2 is negative sowe type -2 in brackets).
Similarly lets add 5b³ to both sides of (2)
-5b³ +...b³=b³
-5b³ +5b³ +...b³=b³+5b³
...b³=6b³ So instead ... we have to type 6.
A zero, or a solution of the quadratic function is c) x = 6 1/3
Write -54x as a difference
9x^2 + 3x - 57x - 19
Factor 3x out
{ 9x^2 + 3x } - 57x - 19
3x (3x + 1)
Factor -19 out
3x (3x + 1) -19 (3x + 1)
Group the equations
( 3x - 19 ) ( 3x + 1 )
Solve for the zeroes
(3x+1) = 0
-1 -1
3x = -1
3x / 3 = x
-1 / 3 = -1/3
x = - 1/3
(3x - 19) = 0
+19 +19
3x = 19
3x / 3 = x
19 / 3 = 6 1/3
x = 6 1/3

Answer:
Sin Z = 8/17
Tan G = 15/8
Cos Z = 15/17
Sin M = 1
Step-by-step explanation:
Sin is equivalent to Opposite over Hypotenuse. For Z, the opposite would be 40. 85 is always the hypotenuse in this problem.
Sin Z = 40/85, simplified it is 8/17
Tan is opposite over adjacent. In this case, the opposite is 75. The adjacent is 40.
Tan G = 75/40, simplified it is 15/8
Cos is adjacent over hypotenuse. In this one, the adjacent is 75. The hypotenuse is 85.
Cos Z = 75/85, simplified it is 15/17.
In Reference to what I said above Sin, I will use the same thing.
Sin M = 1
85/85
