Question 89387: I would like some help with the following problems. Please explain to me how these problems have to be worked out.
Find the value of the following polynomial for the given value of the variable.
-x2-5x-6,x=-3 and = -2( first 2 is a exponent)
What expression raised to the fourth power is 81x12y8z16?( the numers after the variables are exponents)
The cost in dollars of manufacturing w wing nuts is given by the expression 0.07w+13.3 Find the cost when 375 wing nuts are made. What is the average cost to manufacture one wing nut?
Thank you for taking tie to help me out. Thanks.

You can put this solution on YOUR website! Find the value of the following polynomial for the given value of the variable.
-x2-5x-6,x=-3 and = -2( first 2 is a exponent)
------
-2^2-5*2-6
=-4-10-6
=-20
===============
What expression raised to the fourth power is 81x12y8z16?( the numers after the variables are exponents)
x^4 = 81x^12y^8z^16
x = 3x^3y^2z^4
=====================
The cost in dollars of manufacturing w wing nuts is given by the expression 0.07w+13.3
Find the cost when 375 wing nuts are made.
Cost = (0.07*375+13.3)
= 39.55
-------------
What is the average cost to manufacture one wing nut?
39.55/375 = 0.1055
=================
