Answer:
c = 
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
c² = 9² + 6² = 81 + 36 = 117 ( take the square root of both sides )
c = ≈ 10.8 ( to 1 dec. place )
Answer:
Neither
Step-by-step explanation:
To be parallel the lines have to have the same slope. In this case the slopes are not the same.
To be perpendicular, the lines have to have negative reciprocal slopes.
For example, if one slope is 6, then its negative reciprocal i (- 1/6). We do not have this also.
So, the lines are no parallel and no perpendicular.
Answer:
x= -6
Step-by-step explanation:
equation: -10 - 2x = 2x + 14
subtract 14 from both sides: -24 - 2x = 2x
add 2x to both sides: -24 = 4x
divide both sides by 4: -6 = x
