Answer:

B) divide a binomial by a trinomial

Step-by-step explanation:

We know that the polynomials are very nearest to the addition, subtraction and the multiplication part but the same cannot happen under the division part since the division of two polynomials could not become a polynomial it is not necessary condition that it could become a polynomial

So if we divide the binomial by a trinomial therefore it would provides a rational expression and have a negative exponent and a negative exponent is not permitted under the polynomial

Therefore the option B is correct

When calcium metal (Ca) reacts with oxygen gas (O2), it produces the ionic compound calcium oxide (CaO). Write the balanced equa

Vanyuwa [196]

Step-by-step explanation:

Hey there! Down here :D

$\bf{Ca + O_2 \longrightarrow CaO}$

Now , let's balance it by Multiplying 2 on Calcium Side.

$\sf{2Ca + O_2 \longrightarrow 2CaO}$

Is the Required Equation.

Hope it helps :)

<h3>Redox Reaction: Is it?</h3>

Yes, this is because:-

$\sf{2Ca + O_2 \longrightarrow 2CaO}$

Here, Calcium acts as Reducing Agent
And Oxygen is oxidizing agent.
And also, Cao gets oxidized.

It is also a Combination reaction.

$\sf{A + B \longrightarrow AB}$

Here A is Calcium
Here B is Oxygen.

Machine at a manufacturing plant can make 16 of item A per hour or 20 of item B per hour. The machine runs for 24 hours a day. Y

irina [24]

Answer:

A + B = 24

16A + 20B = 434

Step-by-step explanation:

To write a system of equations for this scenario, let's say that A represents the number of hours machine A ran, and B represents the number of hours machine B ran.

The first equation will be:

A + B = 24

because the total number of hours ran is 24.

The second equation will be:

16A + 20B = 434

because the total number of items made is 434.

A + B = 24

16A + 20B = 434

First solve for one variable, and let's just do A.

Using the first equation, A + B = 24, A is equal to 24 - B.

Substitute this value to the second equation.

16 (24 - B) + 20B = 434

384 - 16B + 20B = 434

4B = 50

B = 12.5

Now use this value of B to find the value of A.

A + 12.5 = 24

A = 11.5

Machine A ran for 11.5 hours, and Machine B ran for 12 hours.

Y = x^2 - 4x + 4<br> Find the discriminant.<br> Determine the number<br> of real solutions.

weqwewe [10]

Answer:

The discriminant is 0

There is 1 real solution

Step-by-step explanation:

Use the discriminant formula, D = b² - 4ac

In the equation y = x² - 4x + 4, a is 1, b is -4, and c is 4.

Plug in these values into the formula:

D = b² - 4ac

D = (-4)² - 4(1)(4)

D = 16 - 4(4)

D = 16 - 16

D = 0

So, the discriminant is 0.

With a discriminant of zero, there is one real solution.

So, the number of real solutions is 1.

Count the number of digits after the first digit. this gives you the exponent on the 10. The first number in scientific form has the decimal point after the first digit.

For mercury there are 7 digits after the 5:-

So the Mercury answer is

5.7909175 * 10^7

Follow this procedure for the other planets

The answer for Venus is

1.08208930 * 10^8
