<em><u>Answer:</u></em>
4 or 7 (Check the explanation to see which one your equation <em>actually</em> is.
<em><u>Step-by-step explanation:</u></em>
One thing I want to clarify for you, It's Evaluate, not Avaluate.
Okay so, we want to find the value of 2^3x-1 and we know x = 1.
You didn't really clarify if the expression was 
or 
, so I'll be doing both:
For , we should plug in x to get 
and then simplify to get 
.
2 to the power of 2 or is equal to 2 * 2 or 4.
The second one, , we should plug in x to get 
and then to become 
. 2 to the power of 3 or 
is 8 and then minus 1 is 7.
Answer:
The angle measure for angle c is 138 degrees
Answer: x = 77 degrees, y = 77 degrees, z = 103 degrees
Step-by-step explanation:
Since y and 103 are essentially same side interior angles, they must add up to 180. Therefore, y = 180-103 = 77 degrees.
Opposite angles of a paralellogram are equal.
Therefore, x = y = 77 degrees and z = 103 degrees
