Use the calculator to find the Product
72+k is equal to 180. So if you set up a equation if looks like:
72+k=180
Subtract 72 from both sides
K=108°
Your answer is 108°
The first x=1
the second x=-7
Answer:
3x squared + 2x as you multiply everything in the bracket by what's on the outside of the bracket so it would be 3x multiply by x which equals 3x squared and 2 multiply x which equals 2x
Your absolute value is x+5 so next you would find the answer to 5 minus 8 which is -3 but since -3 and x are on the same side of the equation you have to add 3 to both sides. So the answer is 3
