Answer:
43°
Step-by-step explanation:
(x + 53)° + (x + 74)° + 73° = 180°
(x + 53 + x + 74)° = 180° - 73°
(2x + 127)° = 107°
2x + 127 = 107
2x = 107 - 127
2x = - 20
x = - 20/2
x = - 10

There are no values of X that make the equation true therefore there is no solution
Answer:
C.(6, 4,2)
since every element of B is also an even number,so is an element of C
Distribute
10+4x+4+5
Combine like terms
19+4x
Final answer: 4x+19
Answer:
1) x= -36.
2) x = 0.
Step-by-step explanation:
1) Taking the 3rd power to both sides and using the following exponent law:

we get:

So this tells us that x = -36.
2) We can distribute the power inside every term. So the left side becomes:

Now, the trick here is to remember that
, so replacing 1 with
, which then gives us:
, telling us that 3x = 0 and thus, x = 0.
