Answer: 26 + c = 100

Step-by-step explanation: To find what c equals, we must flip the solution around and subtract it. When we take 100 - 26, we get 74. Therefore, c = 74. I hope this helped! :)

Will factor the express 36xyz + 24xy − 16x by dividing each term by a common fact
sesenic [268]

\\ \bull\tt\longmapsto 36xyz+24xy-16x

  • Divide by 4

\\ \bull\tt\longmapsto \dfrac{36xyz}{4}+\dfrac{24xy}{4}-\dfrac{16x}{4}

\\ \bull\tt\longmapsto 9xyz+6xy-4x

  • Divide by x

\\ \bull\tt\longmapsto \dfrac{9xyz}{x}+\dfrac{6xy}{x}-\dfrac{4x}{x}

\\ \bull\tt\longmapsto 9yz+6y-4

the equation d=1/2n (n-3) gives the number of diagonals D for polygon with n sides. use this equation to find the number of side
alekssr [168]
To solve this problem you must apply the proccedure shown below:

 1. You have that:

 - T<span>he equation d=1/2(n(n-3)) gives the number of diagonals for the polygon.

 - The polygon that has 65 diagonals..

 2. When you clear n, you obtain:

 d=n(n-3)/2
 d=(n^2-3n)/2
 2x65=n^2-3n
 n^2-3n-130=0
 
 3. When you solve the quadratic equation, you obtain:

 n=13

 Therefore, the answer is: 13 sides.  </span>

Frame the polinomial whiose sum product of zeros are -3and2​
Virty [35]

Answer:

P(x) =x² + 3x + 2  

Step-by-step explanation:

You have two zeros, so the polynomial is a quadratic.

The general form of a quadratic is

P(x) = ax² + bx + c

     Sum of zeros = -b

Product of zeros =   c

The polynomial becomes

P(x) = x² - (sum of zeros)x + (product of zeros)

Sum of zeros = -3 and product of zeros = 2, so

P(x) = x² + 3x + 2

The graph of P(x) (below) shows that the zeros are at -2 and -1

     Sum of zeros = -2 + (-1) = -3

Product of zeros = -2 × (-1) =   2

The U.S. Census Bureau conducts annual surveys to obtain information on the percentage of the voting-age population that is regi
Digiron [165]

Answer:

Yes.  We can conclude that the percentage of the employed workers (p1), who have registered to vote, exceeds the percentage of unemployed workers (p2), who have registered to vote.

Step-by-step explanation:

Number of employed persons in the sample = 700

Number of unemployed person in the sample = 300

Number of employed persons who have registered to vote (p1) = 500

Number of unemployed persons who have registered to vote (p2) = 200

Proportion of registered voters who are employed = 500/700 = 71.4%

Proportion of registered voters who are unemployed = 200/700 = 28.6%

This implies that the percentage of registered voters who are employed is more than the percentage of registered voters who are employed.  71.4% (500/700) of the employed registered to vote as against 66.7% (200/300) of the unemployed who registered to vote.

We can conclude that of the 700 registered voters in the sample, 71.4% (500/700) are employed while 28.6% (200/700) are unemployed.

Therefore, the percentage of the employed workers (p1), who have registered to vote, exceeds the percentage of unemployed workers (p2), who have registered to vote.
