Answer: 8x³ - 7x² - 6x + 5
Step-by-step explanation:
8x³ - 7x² - 6x + 5 is a cubic expression.
The variable is x
The variable x has highest power as 3.
8x³ - 7x² - 6x + 5 is a polynomial.
-7x + 4 is a linear expression because highest power of the variable x is 1.
7x² - 5x + 6 is a quadratic expression because the highest power of the variable x is 2.
9x^4 + 8x^3 - 6x^2 - 2x + 11 is a polynomial with the highest power of the variable being 4.
Expression
(5+3)+(5x2)=p
Solution
18
(Step-by-Step)
In this expression we simply have to use basic PEMDAS (Parenthesis Equation Multiplication Division Addition Subtraction) Order.
We start by working out the parenthesis
5 + 3 and 5 x 2
First let's work out our metal and wood paperweights
5+3=8
Simple enough, we have 8 metal AND wood paperweights
Now we have to work out our glass paperweights.
We have twice as many glass as we do metal PW's meaning we need to multiply the 5 metal paperweights by 2
5x2=10
This simplifies and boils our equation down to
8+10
simply solve and add the two and you have your answer
