Answer:
48
Step-by-step explanation:
Create an equation to represent this, where x is the unknown number.
+ 6 = 18
Solve for x, by first subtracting 6 from both sides:
= 12
Multiply each side by 4:
x = 48
So, the number is 48
Answer:
320, -1280
Step-by-step explanation:
r = -4
-5 , 20 , -80 , 320 , -1280
5/6 + 17/2 = 56/2 = 28
11/6 + 11/6 = 22/6 = 3 4/6 = 3 2/3
Answer:
x1 = -6, x2 = -2
Step-by-step explanation:
hope this helps :)
Answer:
x = -7 or x = 2/3
Step-by-step explanation:
I'm assuming you meant solve for x when f(x) = 0.
f(x) = 3x(x + 7) - 2(x + 7)
0 = (x + 7)(3x - 2) -- Both terms have a common factor of (x + 7) so we can group them
x + 7 = 0 or 3x - 2 = 0 -- Use ZPP
x = -7 or x = 2/3 -- Solve
