B - 8x
To find this, combine like terms.
8x - 2x is 6x, then add the two x's on the side to bring it back to 8x.
Hope this helps!
It would be the first one
Step-by-step explanation:
Answer:
irrational
Step-by-step explanation:
9/11 is a decimal that gets repeated so it is irrational
A = LW + 0.5bh
0.5bh = A - LW
b = (A - LW) / 0.5h
Its B
Note to avoid ambiguity its better to put the A - LW in parentheses
To solve this problem you must apply the proccedure shown below:
1- The formula for calculate the area of this rectangle is:

Where
is the length and
is the heigth.
2. Let's call identify the heigth with the variable
.
3. If the length is
longer than the heigth, you have:

4. Therefore, you can write the following polynomial expression:

5. If you know the value of the heigth, you can susbstitute it into the polynomial expression shown above and you will obtain the area.
Therefore, the answer is:
