Answer:
8x + 12 + 2x + 28 = 180
Step-by-step explanation:
just add the angles ABC and CBD then equates to 180
8x + 12 + 2x + 28 = 180
10x = 180 - 12 - 28
x = 140/10
x = 14
therefore, the equation to solve x :
8x + 12 + 2x + 28 = 180
In that case, you have to calculate their Highest Common Factor:
120 & 90.
Their HCF/GCD would be 30.ANS.
Answer:
(-1 , 1)
Step-by-step explanation:
Absicca of midpoint = 4-2 / 2 = -1
Ordinate of midpoint = -4+6 / 2 = 1
Answer:
x = -
Step-by-step explanation:
To find f(g(x)) substitute x = g(x) into f(x), that is
f(g(x))
= f(x + 1)
= 2(x + 1)² ← expand using FOIL
= 2(x² + 2x + 1) ← distribute
= 2x² + 4x + 2
To find g(f(x)) substitute x = f(x) into g(x), that is
g(f(x))
= g(2x²)
= 2x² + 1
----------------------------------------------------------
Equating gives
2x² + 4x + 2 = 2x² + 1 ( subtract 2x² + 1 from both sides )
4x + 1 = 0 ( subtract 1 from both sides )
4x = - 1 ( divide both sides by 4 )
x = -
