Add (-2X) to both sides:
2X + B + (-2X) = C + (-2X)
If we (rearrange) it into B + 2X + (-2X) = C + (-2X)
B + 2X - 2X = C + (-2X)
Since +2X - 2X = 0
B + 0 = C + (-2X)
B = C + (-2X)
B = C - 2X
Answer:
7<em><u>f</u></em>
Step-by-step explanation:
You move 7 to the left of <em>f. </em>
This makes the exact value of <em>f</em>(7), 7<em>f</em>.
Lets try
centimeter is about 1/2 of a inch
if 28 square cm, the book coould be about 4m by 7cm (aoub the size of a recipt)
if 28 square in the book could be about 4in by 7in (regular size)
I would guess 28 square INCHES (cm is too smal)
Answer:
Step-by-step explanation:
A polynomial is a perfect square if has the form:
Its factored form is 
.
We can obtain examples by taking any value of a and b.
For example:
anb 
.
Thus we obtain a polynomial that is a perfect square:
