6/7 because 48 divided by 8 is 6 and 56 divided by 8 is 7
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:
153. 86 units squared
Step-by-step explanation:
3. 14 x 7^2= 153. 86
Answer:

Step-by-step explanation:
We start by subtracting
from both sides of the second inequality:

Therefore, we conclude that:

Therefore, every point that satisfies the system has a
-coordinate greater than
.
