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.

To find Sam's gross pay, you will add the amounts that were deducted back onto the take home pay.

Take home pay ($743) + OASDI ($25) + Medicare ($5) + Income Tax ($27)

Sam's gross income was $800.  

Gross income is the amount of money you make before any deductions.

A test has thirty questions worth 100 points. The test consists of True/False questions worth 3 points each and multiple choice
Vika [28.1K]
So let's break this question down.
You need a bit of both, right? Well we need to calculate how many multiple choices we can do whilst having true/false questions, and not going over or under on points.

So, let's pick a random number, 5. So let's do 8x5, that equals 40.
ohmygoditsrightiwasseriouslyjustguessing
Ok so now we have our number, 5 multiple choice questions. 
The true/false questions should be easy, just do 3x20 and you get 60.

One bar of candy A and two bars of candy B have 777 calories. Two bars of candy A and one bar of candy B contain 783 calories. F
RSB [31]

Answer:

A has 263 calories

B has 257 calories

Step-by-step explanation:

system of equations:

a + 2b = 777

2a + b = 783

I multiplied the first equation by -2 to eliminate the 'a' terms

  -2a - 4b = -1554

+ <u> 2a  + b =    783</u>

         -3b = -771

b = 257

solve for 'a'

a + 2(257) = 777

a + 514 = 777

a = 263
