Answer:
9
Step-by-step explanation:
Use the Pythagorean Theorem which states
a² + b² = c²
then plug in your given terms
a² + 5.6² = 10.6²
find the squares
a² + 31.36 = 112.36
subtract 31.36 from 112.36 to find your a²
a² = 81
then find the square root of 81, which is 9 becuase 9 x 9 is 81
Convert 3 (1/2) into a mixed fraction first and then multiply it by 3:
3(1/2) * 3
(7/2) * 3
21/2
10 (1/2) = answer
Answer:
Group the like terms
6x + 3x - x + 9
Work out the x values together and then add the 9
9x - x + 9
8x + 9
your final answer should be about 8x + 9 as it cannot be simplified anymore
