Answer:
|x + 6| = 2
Step-by-step explanation:
|x - b| = c
b is the centre: (-4-8)/2 = -6
b = -6
c is the distance from the centre
-6 - (-8) = -6 + 8 = 2
Or,
-4 - (-6) = -4 + 6 = 2
| x - (-6)| = 2
|x + 6| = 2
14.35 is Ur answer to Ur Division
Answer: x=3
Step-by-step explanation:
To find the zeros, you want to first factor the expression.
x³+x²-36
(x-3)(x²+4x+12)
Now that we have found the factors, we set each to 0.
x-3=0
x=3
Since x²+4x+12 cannot be factored, we can forget about this part.
Therefore, the zeros are x=3. You can check this by plugging the expression into a graphing calculator to see the zeros.
First find out how many more inches it needs to grow, 54-37.5; It needs to grow 16.5 more inches. If it grows 3 inches a year then you have to do 16.5/3; 5.5. It will take 5.5 or 5 1/2 more years to grow to 54 inches.
