The perpendicular line to x-6y=2, and passing through (2, 4) is y=-6x+16
<em><u>The expressions that are polynomial are:</u></em>
6 + w

z + 1
<em><u>Solution:</u></em>
A polynomial is an expression with variables and coefficients with the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables
1) 6 + w
Here "w" is a variable, hence it is a polynomial expression

This is a polynomial, since it has variables and coefficients and variable with non negative exponent
3) z + 1
This is also a polynomial with variable "z" and has addition operation

Since it has root so it is not a polynomial
X = total amount of people
80% of x = 540
.8x = 540
x = 675
There were 675 people
Answer:
A = 94.6ft^2
Step-by-step explanation:
In order to be able to find the area of a trapezoid or any quadrilateral shape we need to use the equation:
A= a+b/2h
As we know we have the number base 7.7ft, base 14.3ft, and height of 8.6ft so then we take these numbers :
7.7 + 14.3/2 x 8.6 = 94.6
