Sorry but, there’s nothing attached so I can not help you.
The correct answer is Choice A.
This is an example of an exponential equation, so we need the formula

.
The a value is the starting value of 100. The b value must be a decimal lower than 1 because it is decreases.
If you substitute in 8 for x, you will see that the output is about 50 (half of 100).
Answer:
x =105002
Step-by-step explanation:
5x=525010
Divide each side by 5
5x/5=525010/5
x =105002
Answer:
A = 1,307 cm^2
Step-by-step explanation:
Formula of Surface Area of a Rectangle:
A = 2 (lw + lh + wh)
length*width = (20)(23) = 460
length*height = (23)(4.5) = 103.5
width*height = (20)(4.5) = 90
A = 2 (460 + 103.5 + 90)
A = 2(653.5)
A = 1,307 cm^2
