The expression 40x2 – 65x + 50 represents the sum of the interior angles of a regular pentagon in degrees. If the interior angle

s of the pentagon are equal, which expression represents the measure of two angles?
2x2(20 – 32x + 25x2)
2(8x2 – 13x +10)
5x2(8x2 – 13x + 10)
5(3x2 – 8x + 5)

Answer:

<u>The answer is</u>: <u>5x2 (8x2 - 13x + 10).</u>

<u />

Explanation:

The expression 40x2 - 65x + 50

The expression that represents the measure of two angles is this:

5x2 (8x2 - 13x + 10);

(5 x 8x2) - (5 x 13x) + (5 x 10);

40x2 - 65x + 50

<u>The answer is</u>: <u>5x2 (8x2 - 13x + 10).</u>

nonliving the heat from the hot plate is causing the gel like substance to move it's the same thing with liquid nitrogen how it seems to bounce off the floor it's because liquid nitrogen is super cold and the heat basically excites the electrons in the liquid nitrogen making it bounce off the floor same with the gel like substance the electrons in the gel substance are getting excited by the heat and jumping up and down but the substance itself is not alive

Which part of the chemical equation is incorrect
ikadub [295]

The part of the chemical equation is incorrect is The solution is 10 02, it ought to de 1302.For carbon, on each aspects, there are eight carbon atoms.For hydrogen, on each aspects there are 20 hydrogen atoms.

<h3>What a part of a chemical equation are you able to by no means alternate?</h3>

When you stability an equation you could most effectively alternate the coefficients (the numbers in the front of molecules or atoms). Coefficients are the numbers in the front of the molecule. Subscripts are the smaller numbers observed after atoms. These can not be modified while balancing chemical equations.

The complete question is Which part of the chemical equation is incorrect which is 2C4H10+ 10O2 - 8CO2+10H2O.

  1. To realize if a response is properly balanced among the reactants and the products, you need to calculate the wide variety of atoms of every detail on each aspect of the response and to test if they may be equal.
  2. For oxygen, there are 20 oxygen atoms withinside the reagents and 26 withinside the products, so it's miles essential to grow the wide variety of oxygen withinside the reactants (with out touching the others). For this we positioned thirteen 02 withinside the reactants rather than 10, to have 26 oxygen atoms on every side.

Do you think geothermal energy is a renewable resource? Why or why not? What are the benefits of using this energy to power home
Keith_Richards [23]
Geothermal is a renewable energy, because it is from the heat produced by the earth. The earth gets heat from the sun, which will be there for the next million of years. Geothermal has benefits, because if we harness the use of it, instead of mining out all of our coal and oil, we can use this for a long run, and only leave non-renewable energy resources for backup. However, there are consequences to communities and surroundings. The geothermal only benefits when the earth is warm. When the earth becomes too warm, we wouldn't even need the energy anymore cuz everythings dead. So we can use this, but overall we must try to lower the amount of resources that produce this thing as possible.. ( use other renewable energy)

hope this helps

How are the names of binary ionic compounds determined?
Alexandra [31]
Naming ionic compounds<span> with transition metals isn't too hard either. They are</span>named<span> like the </span>binary compounds<span>, with the cation first, then the anion with -ide added to it, but you have to take into account the variations of the metal </span>ions<span>. You do this by adding Roman numerals in parenthesis to the cation.</span>
