Answer:

Step-by-step explanation:

0 is the first whole number

The 5 smallest consecutive whole numbers:

0 , 1 , 2 , 3, 4

Add

Hiro bought a small carton of milk at lunch. If the approximate dimensions of the milk carton are shown what is the minimum amou

faltersainse [42]

Answer:

$C.\ 104\ in^2$

Step-by-step explanation:

At first, the question looks like an optimization problem, but since all the dimensions of the carton are given, we only have to compute the total area of the given figure.

Let's calculate the front (and back) areas, which are rectangles

$A_1=(6.5)(3)=19.5\ in^2$

Now with the lateral rectangles which happen to have the very same dimensions

$A_2=19.5\ in^2$

Next, we compute the front and back triangles of base 3 in and height 1.5 in

$A_3=\frac{1}{2}(3)(1.5)=2.25\ in^2$

Now, the lateral inclined rectangles of base 3 in and height 2 in

$A_4=(3)(2)=6\ in^2$

Finally, the base rectangle who happens to be a square of side 3 in

$A_5=(3)(3)= 9\ in^2$

This last area, unlike all others, is not doubled because its counterpart is inside the carton and is not part of the lateral area

Our total area of cardboard is

$A_t=2(19.5)+2(19.5)+2(2.25)+2(6)+9=103.5\ in^2$

The closest option to this answer is

$C.\ 104\ in^2$

Which of the following shows that polynomials are closed under subtraction when two polynomials, (5x2 3x 4) − (2x2 5x − 1), are

Verizon [17]

The closure property under subtraction is shown when the correct

result from the subtraction of polynomials is also a polynomial.

Response:

The option that shows that polynomials are closed under subtraction is; <u>3·x² - 2·x + 5 will be a polynomial</u>.

<h3>How is the option that shows the closure property found?</h3>

The closure property under subtraction for the polynomials is condition

in which the result of the difference between two polynomials is also a

polynomial.

The given polynomials being subtracted is presented as follows;

(5·x² + 3·x + 4) - (2·x² + 5·x - 1)

Which gives;

(5·x² + 3·x + 4) - (2·x² + 5·x - 1) = 3·x² - 2·x + 5

Given that the result of the subtraction, 3·x² - 2·x + 5, is also a

polynomial, we have, that the option that shows that polynomials are

closed under subtraction is; <u>3·x² - 2·x + 5 will (always) be a polynomial</u>.
