Answer:
A. 
B. 
Step-by-step explanation:
A. The area of the shaded region = area of the whole large square - area of the 4 smaller squares
= (5x*5x) - 4(4*4)
Area of shaded region = 
B. The expression, , is the difference of two perfect squares, 25x² and 64. Therefore, apply the rule of factoring difference of two perfect squares.
Thus, 
Therefore, the expression of the are of the shaded region can be expressed in factored form as:
First, you solve the square root:
Knowing that the square root of a negative number doesn't exist:
is your answer.
Hope it helped,
Happy homework/ study/ exam!
Answer: domain (7,8)
Step-by-step explanation: range is the Y-value and domain is the x-value
The option that describes h(x) is B. The function h(x) is increasing on the interval (5, ∞).
<h3>What is a function?</h3>
In mathematics, a function simply means a relation between the inputs and the outputs.
In this case, the information given is that h(x) is 2 times the square root x minus 5. The square root of the negative number cannot be taken, therefore, the domain of the function is restricted.
Since the domain is restricted, the function is increasing. Therefore, the function h(x) is increasing on the interval (5, ∞).
