What is the coefficients of x² in (2-3x) (x²-5)​

Mathematics

aniked [119]3 years ago

Answer:

+2

Step-by-step explanation:

=> (2-3x)(x^2-5)

=> (2x^2-10-3x^3+15x)

<em>Arranging it in descending order</em>

=> -3x^2+2x^2+15x-10

<u><em>So, the coefficient of x² in this expression is +2</em></u>

This depends if you are supposed to simplify the binomials first:

If you leave it in the form provided then the coefficient would be 1

However, you can multiply the binomials together in order to simplify the expression:

(2 - 3x)( {x}^{2}  - 5)

(2  \times  {x}^{2} ) + (2 \times  - 5) + ( - 3x \times  {x}^{2} ) + ( - 3x  \times  - 5)

{ - 3x}^{3}  +  {2x}^{2}  + 15x - 10

Which then shows the coefficient would be 2

So it all depends on the directions provided, I would assume the correct answer is 2 if the directions are the exact same as provided on Brainly.

When 3 is subtracted from one third of a number less than 6. Which inequality and solution represents this sitution?
kenny6666 [7]

Answer:

1/3(n) - 3 < 6; n < 27

Step-by-step explanation:

" 3 subtracted from one third of a number"

= 1/3(n) - 3

given that this is less than 6:

1/3(n) - 3 < 6

1/3(n) < 6 +3

1/3(n) < 9

n < 27

PLEASE HELP AND SHOW WORK PLEASE.

Inequalities help us to compare two unequal expressions. There exists no solution to the given set of inequalities.

<h3>What are inequalities?</h3>

Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.


The given Inequalities can be solved as,

5 - x > 7

-x > 7 - 5

-x > 2

x < -2

2x + 3 ≥ 13

2x ≥ 10

x ≥ 5

As per the solution of the two inequalities, the value of x should be less than -2 but at the same time, it should be more than or equal to 5, which is impossible. Thus, there is no solution for the given inequalities.

This can be confirmed by graphing the two inequalities, as shown below. Since there is no area in common between the two inequalities, there exists no solution to the given set of inequalities.

What is the measure of angle G?<br><br>Please help I’m so confused
Nana76 [90]

Answer:

angle G is 45 degrees

Step-by-step explanation:

all sides of a triangle add up to 180 degrees. looking at the triangle, the angles that we are provided are E and F. E is 90 degrees, and F is 45 degrees. If you add those together, we get 135. then, subtract 180 from 135, and you get your answer, which is 45 degrees.

also, it says on the smaller triangle in the bottom left.

hope this was helpful :D
