8 as you round up 405 to 400 and divide by 50 and get 8
25 is the length of x, using the 30-60-90 special triangle method
Add 4 to the whole equation
-10 + 4 < 2x < 8 + 4
Simplify
-6 < 2x < 12
Divide the whole equation by 2
-6/2 < x < 12/2
Simplify
<u>-3 < x < 6</u>
Answer:
Isolate the variable by dividing each side by factors that don't contain the variable.

Step-by-step explanation:
The answer is 95.
First: find the area if the whole rectangle. To do so you would multiply lxw (10x12)
Second: you would find the area of the square. Squares have perfect sides so you would multiply 5x5.
Last: take the sums of both equations. So the it would be 120-25=95.
