Answer:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
4*x-12-(6*x-18)=0
Step-by-step explanation:
Pull out like factors :
-2x + 6 = -2 • (x - 3)
Answer:
Step-by-step explanation:
A = 9
chord length c = 18
height h = 4
r = (c²+4h²)/(8h) = 12.125

Answer:
81
Step-by-step explanation:
9*(x + y) = 10x + y
9x + 9y = 10x + y
0 = x - 8y
8y = x
=======
y = 1
x = 8
x + y = 8 + 1 = 9
9*9 = 81
So 81 is 9 times the sum of it's digits.
