Answer:
112°
Step-by-step explanation:
to be supplementary angles must equal 180°
so to solve just subtract 68° from 180° which equals 112°
replace the numbers inside () for x
f(4) = -4(4)-3 = -16 -3 = -19
G(-4) = 2(-4)^2 -3(-4) = 44

Answer:
x=0
Step-by-step explanation:
Solve for x.
5(x - 3) + 4(x + 3) = 3(x - 1)
Distribute
5x -15 +4x +12 = 3x-3
Combine like terms
9x -3 = 3x-3
Add 3 on each side
9x -3+3 = 3x-3
9x = 3x
Subtract 3x from each side
9x-3x = 3x-3x
6x =0
Divide by 6
6x/6 = 0/6
x=0
Answer:
14.25 units
Step-by-step explanation:
Area of a square= 
Solving the equation using quadratic equation then as attached
x=14.25 units
To prove
x-3=14.25-3= 11.25 units
area=11.25*11.25=126.5625 sq units
