Answer:
Step-by-step explanation:
For calculating the sales tax of a product, it is required to first multiply the original cost price of the product by the sales tax percentage.
Once the sales tax has been computed add it to the original cost price in order to determine the total cost of the product.
The formula of final amount is:
Here,
A = final amount
P = original cost price
S = sales tax percentage
Answer:
122 or (3x-4).
Step-by-step explanation:
First, let's take a look at the polygon
The polygon has 5 sides.
We can calculate it's sum of interior angles by using (n-2)*180
Here, number of sides(n)=5
Therefore, (n-2)*180=(5-2)*180=3*180=540
Now that we got that out of the way, let's solve for x
2x+9+3x-8+3x-4+3x-10+2x+7=540
or,13x-6=540
or,13x=546
or,x=42
Now, solve for each interior angle,
2x+9=93
3x-8=118
3x-4=122
3x-10=116
2x+7=91
The largest here s 122 which is 3x-4.
SO, the largest interior angle=122 or (3x-4).
After subtracting 3 from 7, and dividing 4 by 2, you should end up with x=2.
Answer:
2(n+2x-6)
Step-by-step explanation:
n x 2+4x-4-8
Answer:
polynomial of degree 10
Step-by-step explanation:
The degree of the polynomial is the sum of the exponents, that is
y³ → has degree 7 + 3 = 10
