\frac{-18z^{7}y^{5}-9z^{9}y^4+18z^6y^8}{9zy^{2} }= -2z^6y^3-z^8y^2+2z^5y^6


When variables with exponents are divided by each other, you subtract the exponents.

For example:

\frac{x^2}{x^1} = x^{2-1} =x^1

\frac{x^5}{x^3} =x^{5-3} = x^2

Vlad1618 [11]
Decibel is directly proportional to number of cars passing the point. That is,

69 db ----- 139 cars
x   db ----- 17 cars

x = number of cars passing the point per minute on a weekend.

Then,
x= (69*17)/139 = 8.43 db ≈ 8 db

Help me I don’t get this
andre [41]

Step-by-step explanation:

Area = 8 × 5

Area = 40^2

Perimeter is the length around the edges

Therefore it is 8+8+5×5 (since there are 4 edges)

Perimeter = 2×8 + 2×5

= 40 + 10

= 50cm

The coefficient of 8.2 N is<br> 8<br> 2<br> 16
Aliun [14]

Answer:

2

Step-by-step explanation:

A coefficient is the number placed before the variable. The variable gets multiplied by the coefficient.

The format is not exactly clear with the expression in the question.

Assuming the expression is '8 * 2n', the coefficient would be 2.

'n' is getting multiplied by '2'.

'8' does not have a variable next to it, so it is just a term in the expression.

The product of 8 and 2 is 16. 16 is not in the expression.

If the expression was '8.2n', 8.2 would be the coefficient.
