Answer:
30%
Step-by-step explanation:
Initial area is 40 square feet
Final area is 28 square feet
Difference between the initial and final areas will be 40-28=12 square feet
Taking the initial area as the base area and expressing the area change in percentage then the percentage decrease will be equivalent to

Therefore, the decrease in area expressed as a percentage is equal to 30%
Not quite sure what you mean by brackets, but you can get the solution to this equation in a few steps:
<span>(-2x - 1)</span>² <span>= 0 ... square root both sides to eliminate the squared binomial
</span>√(-2x - 1)² = √0 ... simplify; the square is canceled out and the root of 0 brings you back to 0
-2x - 1 = 0 ... solve like a two-step equation
-2x = 1
x = -1/2 is your x-value.
The relationship between centimeters and inches is linear. The equation in the relationship is:
y= 2.54x , with x as inches and y as centimeters.
The graph for this equation results to a straight line. This equation has a degree of one.
Answer:
a is 5 so the perinmeter is 30
