Answer:
I think it should be x+4
Step-by-step explanation:
because if u r finding for the overall segment we will add the x units with the four units.
The correct answer is -7x^2-28x
Hope this helps! (^2 is an exponent!)

Tip!
Base is your platform you put your block on imagine your phone on the desk if you place it with the screen up the back of your phone is the platform. If you have a rectangle always try to make it into a square if its possible.
Saying that:
A)
Base= 5 units
Height= 4 units
B)
Base=5 units
Height=4 units
The behavior of the graph of I and what it means in context can be explained below:
<h3>What is Sound intensity?</h3>
Sound intensity, serves as the power that is been carried by sound waves per unit area and this is usually in the direction perpendicular to that area.
we were given the function
r represent the Distance from the source of sound
P represent the Power of the sound
when there is increase in the distance from the source the intensity moves to zero.
we can see that there is is an inverse proportion between the Intensity and the distance r which implies that The intensity decreases when the distance increases.

Answer:
Step 3 they took the square root incorrectly
Step-by-step explanation:
5 ( x-2)^2 +6 = 86
Subtract 6 from each side
5 ( x-2)^2 +6 -6= 86-6
5 ( x-2)^2 = 80
Divide each side by 5
5 ( x-2)^2 /5 = 80/5
(x-2)^2 = 16
Take the square root of each side
sqrt((x-2)^2) = ±sqrt(16)
x-2 = ±4
