Answer:
(C)The square root of terms separated by addition and subtraction cannot be calculated individually.
Step-by-step explanation:
In Step 7:

The expression
cannot be written as
. This is as a result of the fact that square roots of terms separated by addition and subtraction cannot be calculated individually.
Take these examples:

Simple...
you have: x-3y=18
You want to convert it into slope-intercept form or y=mx+b form-->>>
x-3y=18
Isolate the variable-->>
x-3y=18
-x -x
-3y=-x+18
Now simply divide...
y=
Answer:
a = -2
b = 5
Step-by-step explanation:
We can identify the right side of the equation as completing the square. So, we simply complete the square for x² - 4x + 9 to find our answer,
Step 1: Isolate xs
x² - 4x = -9
Step 2: Complete the square
x² - 4x + 4 = -9 + 4
(x - 2)² = -5
Step 3: Move -5 over
(x - 2)² + 5
And we have our answer!
Answer:
multiply 5 x 4 = 20
multiply the dimensions of the lighter square
after all the multiplying you subtract your answers and you should get the VERY final answer
*don't add because it's area; just multiply
Answer:
The end result would be 0>-11
Step-by-step explanation:
Subtract 7 from each number and then just write it again.
7 - 7 = 0
-4 - 7 = -11
0>-11
