The answer is A! If 1/3 is gone, there’s 2/3 left. To find how much 2/3 is, you would multiply 80 by 2/3
Answer:
( x + 3 )² - 27
Step-by-step explanation:
x² + 6x = 18
→ Minus 18 from both sides to get a quadratic equation
x² + 6x - 18
⇒Completed square from is ( x + a )² + b
⇒The value of 'a' will always be half the 'b' value in the equation
ax² + bx + c
→( x + 3 )² + b
Expand out the equation to find 'b'
x² + 6x + 9
We have do something to get from 9 to - 18 which -27
So the answer is ( x + 3 )² -27

Answer:
Option B.
.
Step-by-step explanation:
The given equation is kx - 4 = 9
We will add 4 on both the sides of the equation
kx - 4 +4 = 9 +4
kx = 13
Now we will divide by k on both the sides of the equation
![x = \frac{13}{k}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B13%7D%7Bk%7D)
Therefore Option B x = 13/k is the right answer.
