How will we expand this expression? Is there a property in mathematics that we can use to expand this?
The answer is "Yes". There is indeed a property that we can use, and it's called "The distributive property".
[tex]\ast[/tex] As the name implies, we distribute a number, variable, or a combination of the two.
We distribute by multiplying this number or variable or whatever we need to distribute by the expression inside the parentheses, as follows :

which results in

Can someone please help? the value of a plot of land increases 8% every year. the value is $350000 now, and the owner wants to sell it when the value is at least $570000. shanna writes an exponential function of the form, v(t)=a*b^t, to model the value,v, of the land in t years. i need to know what the value of b is and the domain
Answers
The value of b in the exponential function which is formed by Shanna for the price of land is 8% or 0.08.
What is percentage increase ?Percentage increase is the amount added to the initial value in the percentage part.
The value of a plot of land which is increases 8% every year has the current value of $350000.
The final value owner wants is $570000. Shanna writes an exponential function of the form, to model the value,v, of the land in t years as,
[tex]v(t)=a\times b^t[/tex]
Here, in this exponential function the value of a is fixed or initial term which is $350000 and the value of b is the constant term which is change factor. Here, the value of b is 8%.
b=8%
b=8/100
b=0.08
Thus, the value of b in the exponential function which is formed by Shanna for the price of land is 8% or 0.08.

It takes 6 hours for 20 workers to seed 40 acres.
How long would it take 10 workers to seed 90 acres?
Answers
Answer:
27 hours
Step-by-step explanation:
We are given the information that it takes 6 hours for 20 workers to seed 40 acres. This means that with 20 workers the rate is 40 acres in 6 hours, or 40/6 = 6.67 acres per hour. When we only have 10 workers, we only have half as many people, therefore the rate will be twice as slow, so with 10 workers, the rate is 6.67/2 = 3.34 acres/hour.
To find how long it takes to seed 90 acres we just need to divide 90 by the rate. 90/3.34 = 27 hours.

Step-by-step explanation:
Here is a diagram and its corresponding equation. Find the solution to the equation. Tape diagram, 4 parts labeled x + 7, total 38. 4(x+7)=38
Answers
The distribute multiplication property allows us to multiple the 4 by the “x” and the 4 by the 7.
This brings us to
4x +28 = 38
Now we must subtract the 28 to the 38 in order to begin getting the “x” by itself.
4x = 10
Now divide by 4 to fully get the X alone
4x/4 = 10/4
x= 10/4 = 5/2 = 2 1/2

One year, the population of a city was 73,000. Several years later it was 85,410. Find the percentage decrease
Answers
The percentage decrease is 14.52% if, one year, the population of a city was 73,000. Several years later, it was 85,410.
What is the percentage?It is defined as the ratio of two numbers expressed in the fraction of 100 parts. It is the measure to compare two data, the % sign is used to express the percentage.
The initial population = 85410
The final population = 73000
The decrease = (85410 - 73000)/85410 = 0.1452
The percentage decrease = 0.1452×100 = 14.52%
Thus, the percentage decrease is 14.52% if one year, the population of a city was 73,000. Several years later, it was 85,410.
