Find the product given polynomial p(x) =3xsquare plus 2x -x square plus 8 and q (X) = 7x plus 2​

Answer»

Step-by-step explanation:

p(x) = 3x² + 2x -x² + 8 = 2x² +2x +8

Q(x) = 7x+2

p(x)× q(x)

(2x² +2x +8)×(7x+2)

2x+3y = 12,5x-3y=9 ans plz​

Answer»

GIVEN:-

EQUATION:-

2x + 3y = 12

5x - 3y = 9

To find:-

The VALUE of x and y

Method Used:-

Substitution method.

Solution:-

\sf{2x + 3y = 12\longrightarrow[i]}

\sf{5x - 3y = 9\longrightarrow}

From equation[i]

\sf{2x + 3y = 12}

= \sf{2x = 12-3y}

= \sf{x = \dfrac{12-3y}{2}}

SUBSTITUTING the value of x in equation[ii]

= \sf{5x - 3y = 9}

= \sf{5\bigg(\dfrac{12-3y}{2}\bigg) - 3y = 9}

= \sf{\dfrac{60-15y}{2} - 3y = 9}

= \sf{\dfrac{60-15y-6y}{2} = 9}

= \sf{60-21y = 9\times2}

= \sf{-21y = 18-60}

= \sf{-21y = -42}

= \sf{y = \dfrac{-42}{-21}}

= \sf{y = 2}

Now,

Putting the value of y in equation[i]

\sf{2x + 3y = 12}

= \sf{2x + 3\times 2 = 12}

= \sf{2x + 6 = 12}

= \sf{2x = 12-6}

= \sf{2x = 6}

= \sf{x = \dfrac{6}{2}}

= \sf{x = 3}

\sf{\therefore x = 3\: and\: y = 2}

______________________________________

Verification:-

Let us put the value of x and y in both the equations simultaneously.

For equation[i]

= \sf{2x + 3y = 12}

= \sf{2\times3 + 3\times 2 = 12}

= \sf{6 + 6 = 12}

= \sf{12 = 12} [Verified]

For equation[ii]

= \sf{5x - 3y = 9}

= \sf{5\times 3 - 3\times 2 = 9}

= \sf{15 - 6 = 9}

= \sf{9 = 9} [Verified]

Hence Verified!!!!

Write an algebraic expression for this puzzle sequencethink of a number add 10double itsubtract 10divide by 2take away the number first thought ofwhat answer do we always obtain?

Answer»

Step-by-step explanation:

CHOOSE a number from 1 to 70 and then divide it by 7. (I’ll be nice and let you use a calculator, but you’ll NEED one that has at LEAST seven decimal places.) If your total is a whole number (that is, no digits after the decimal POINT) divide the answer by 7 again. Is there a 1 somewhere after the decimal point? I predict that the number after the 1 is 4. Am I right? Now add up the FIRST six digits after the decimal point.

उत्तर

√2 = 1.414

√3 = 1.732

∴ √2 < 1. 5 < √3

\displaystyle \sf{1.5 = \frac{3}{2} }

\therefore \: \: \displaystyle \sf{ \sqrt{2} \: < \: \frac{3}{2} \: < \sqrt{3} \: }

Out of following equations, which has 3 as solutionx2+2x-15x ,,x2-x-6=0,, x2+x+6=0,, x2-x+6=0,, x2+x+6=0​

Answer»

Step-by-step EXPLANATION:

  • x² + 2X -15 = 0

discriminant = b²-4ac

a=1 , b=2 , c = -15

d = (2)² - 4(1)(-15)

d = 4 - (-60)

d = 4 + 60 = 64

d = 64

therefore this equation have real and district solutions

  • x²-x-6=0

discriminant = b² - 4ac

a=1, b = -1 , c = -6

d = (-1)² - 4(1)(-6)

d = 1 - (-24)

d = 1 + 24 = 25

d = 25

therefore the equation have real and DISTINCT solutions.

  • x² + x + 6 =0

discriminant = b² - 4ac

a=1, b=1, c=6

d= (1)² - 4(1)(6)

d = 1 - 24

d = -23

therefore the equation doesn't have real equations.

  • x² - x + 6 =0

discriminant = b² - 4ac

a= 1, b= -1 , c = 6

d = (-1)² - 4(1)(6)

d = 1 - 24

d = -23

therefore the equation doesn't have any real equations.
