1 hundred can also be 10 tens so when you add 10 tens and 4 tens you 14 tens and that is the same thing as 14 tens
144=(x+7)^2 take the square root of both sides...
12=x+7 subtract 7 from both sides...
x=5
So the original was a 5m square.
...
255=WL and you are told that W=L+2 so the equation becomes:
255=(L+2)L
255=L^2+2L
L^2+2L-255=0
L^2+17L-15L-255=0
L(L+17)-15(L+17)=0
(L-15)(L+17)=0 Since L>0...
L=15yd, and since W=L+2, W=17yd so
length=15, width=17yd
The correct answer is D.
The area is base x height which in this case is 14 x 8 = 112 which is answer choice D.
Hope this helps.
Answer:

Step-by-step explanation:
Given:
The given inequality is:

The given inequality has variable 'x' on both sides of the inequality.
In order to solve such inequalities, we bring the variables on the same side as the first step in solving for 'x'.
Therefore, we could either add
on both sides or add
both sides to bring the variable terms on same side.
If we add
both sides, we get:

So, among all the given options, third option matches the above inequality.
Therefore, the first step in solving the given inequality is 
Arithmetic sequence
Explanation
An arithmetic sequence is a list of numbers with a definite pattern. If you take any number in the sequence then subtract it by the previous one, and the result is always the same or constant then it is an arithmetic sequence
Step 1
Let


so, the difference is always the same, 2
Hence, the answer is a Arithmetic sequence
