Answer:
7 < x < 9
Step-by-step explanation:
x^2 – 16x + 63 < 0
this is a parabola that opens up.
The parabola will be < 0 for values between the roots.
to picture this see the graph below.
Factor
(x - 7)(x - 9) < 0
Roots
x = {7, 9}
solution
7 < x < 9

Answer:
x = 91
Step-by-step explanation:
The sum of the 4 interior angles of a quadrilateral = 360°
Sum the 4 angles and equate to 360, that is
x + 10 + x - 10 + x + 6 + x - 10 = 360 , then
4x - 4 = 360 ( add 4 to both sides )
4x = 364 ( divide both sides by 4 )
x = 91
