A coworker notices that the original box costs $0.22 per square foot of cardboard and the new box cost $0.15 per square foot of cardboard. She claims that the new bow must cost less than the original box explain why your co worker claim is incorrect?
(PLEASE HELP ASAP I’LL GIVE YOU BRAINLIEST)

Answers

Answer:

she is correct

Step-by-step explanation:

if you subtract 15 from 22 you get 6 cents leftover

Yes , the new box must cost less than the original box be $ 0.07

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

The cost of the original box = $ 0.22

The cost of the new box = $ 0.15

So , the difference in cost = $ 0.22 - $ 0.15

A = $ 0.07

Hence , the cost of the new box is less

6x^2 - 18x - 240 = 0
solve for x.
Find solutions that are greatest to least.

Answers

6x^2 -18x -240=0 is a quadratic equation. Therefore you can use the quadratic formula to find ‘x’.

The greatest solution will be 8 and least solution will be -5.

A polynomial equation is given which is 6x² - 18x - 240 = 0

We have to find out the solutions that are greatest to least.

What do you mean by the quadratic equation ?

Quadratic equation is a polynomial equation whose highest degree is two . It is expressed in the form of ax² + bx + c = 0.

As per the question ;

Equation is ;

6x² - 18x - 240 = 0

Let's take 6 as common ;

6 ( x² - 3x - 40 ) = 0

x² - 3x - 40 = 0

This can be written as ;

x² - 8x + 5x - 40 = 0

x ( x - 8 ) + 5 ( x - 8 ) = 0

( x + 5 ) ( x - 8 ) = 0

x + 5 = 0

and

x - 8 = 0

So ;

x = - 5 and 8

Thus , the greatest solution will be 8 and least solution will be -5.

Find all roots of the polynomial function f(x) = 2x^4-x^3-13x^2+5x+15

Answers

Answer:

Roots are : 1, -7 and -7

Step-by-step explanation:

When we put x = -1 in F(x) it is equal to 0

Thus, (x + 1) is factor of given function.

When we divide F(x) by (x + 1) it gives the value (x² - 6x - 7)

factorizing the work x² - 6x - 7 by middle term splitting.

> x² - 6x - 7 = x² - 7x + x - 7

> x(x - 7) + 1(x - 7)

> (x + 1) (x - 7)

then, x³ - 5x² - 13x - 7 = (x + 1)(x + 1)(x - 7)

x = -1, -1, 7 the factor.
