Answer:
sqrt(5) and sqrt (9)
Step-by-step explanation:
if you split it up it would be the square root of both of those numbers, and sqrt(9) is a perfect square (it equals to 3)

Answer: Club A
EXPLANATION
Given,
Club A charges $12 for membership and $2 for each rented video.
The deal in Club A can be represented by the function, f(x) = 12 + 2x
Club B charges $4 for membership fee and charges $4 for each rented video.
The deal in Club B can be represented by the function, f(x) = 4 + 4x
To determine which video rental club is the better deal
First, we find the number of videos where the amount spent will be the same
That is, when 4 + 4x = 12 + 2x
Subtract 4 from both sides of the equation
4 + 4x – 4 = 12 + 2x – 4
4x = 8 + 2x
Subtract 2x from both sides of the equation
4x – 2x = 8 + 2x – 2x
2x = 8
Divide both sides by 2
2x/2 = 8/2
x = 4
Since the deals for club B and club B will be of equal expense by the time a total of 4 videos have been rented, the better deal is the one that is cheaper when more than 4 videos have been rented.
Take a random value of x that is greater than 4, say 6
For the deal in Club A, f(x) = 12 + 2x
= 12 + 2(6)
= 12 + 12
= $24
For the deal in Club A, f(x) = 4 + 4x
= 4 + 4(6)
= 4 + 24
= $28
Since the deal in Club A is cheaper on the long run (i.e for 5 videos and above), it is a better deal than that of Club B
x can only equal -3.2.
x can only equal 7.4.
O x can equal -3.2 or -7.4.
O x can equal -3.2 or 7.4.
Answer: x can equal -3.2 or -7.4.
Step-by-step explanation:
The correct expression is:
2|x+5.3|=4.2
So, we have an absolute value equation, where it can be positive or negative:
2 (x+5.3)=4.2
2x+10.6 =4.2
2x=4.2-10.6
2x = -6.4
x= -6.4/2
x = -3.2
2[-(x+5.3)]=4.2
-2x-10.6 =4.2
-2x= 4.2+10.6
-2x= 14.8
x= 14.8/-2
x= -7.4
x can equal -3.2 or -7.4.
