Polynomial P(x) = x² - 6 x + aGivenα andβ are the roots. To find a , if 3α + 2β = 20. ---(1)

From the quadratic expression: α +β = 6 ---(2) and αβ = a --- (3)

Multiply equation (2) by 2 and subtract from (1) to get: α = 20 -12 = 8

Substitute this value in(2) to get: β = 6-8 = -2

Substitute these in (3) to get: a =αβ = -16.

use the fact sum of angles in triangle is 180i) x = 180 -60-50 = 180- 110 = 70ii) x = 180- 90-30 = 60iii) x = 180 - 30 - 110 = 40

thanx

question is not clear please post the complete question

Red line 2x + y = 8Blue line x + 1 = 2y

Point of intersection is (3,2) which is the solution

x-15/3=x-3/55x-75=3x-92x=64x=32

Red line : 5x - y = 2Blue line : x-y = -2 They intersect at (1,3) so, solution is x = 1 and y = 3

thanks brother

So red line is x - y = 1 andblue line is 2x + y = 8 There point of intersection is (3,2)

solution of this equations is(3,2)

it is 4500 1500 × 3 is 4500

1500×3 4500₹ is the answer

1500×3=4500₹ is answer.

1500+1500+1500=4500 is the answer

1500x4500=4500 Rs answer

not right answer yrrr 😊

eska answer 12th hai

sorry for inconvenience actually I calculated whether the sum of sequence can be 47.

1/3-√8-1/√8-√7+1/√7-√6-1/√6-√5+1/√5-2=5Now,1/3-√8 = 3+√8, 1/√8-√7 = √8+√7,1/√7-√6 =√7+√6,1/√6-√5 = √6+√5,1/√5-2 =√5+2∴ 1/3-√8-1/√8-√7+1/√7-√6-1/√6-√5+1/√5-2= 3+√8-√8-√7+√7+√6-√6-√5+√5+2=3+2 = 5Hence proved.

x= 5/19+7/19= 12/19

Let 1/(x+y)=m ; 1/(x-y)=n ; So the equations become, 35m+14n=19 (1)14m+35n=37 (2)Adding 1 and 2,49m+49n=567m+7n=8 (3)Subtracting 1 and 2,21m-21n=-18 7m-7n=-6 (4)Adding 3 and 4,14m=2 m=1/7 So x+y=7. (5)1+7n=8 n=1 x-y=1. (6)Adding 5 and 6,2x=8 ,x=4,4+y=7 y=3.

The value of sin90 is 1.

252/420 is the correct answer

9/15=0.6 is the answer because 4 in the numerator and 4 in the denominator cancels out and similarly 7 in the numerator cancels out 7 in the denominator.

9/15*1= 9/15=0.6 ans

9/15*1=9/15=0.6 answer

2.714 is right answer this question

9/15*1=9/15=0.6 answer

2207/28 is the right answer to your question

I hope it helped you .😅

2207/28 is the correct answer of the following

ax+by+c =0

=> by = -ax-c=> y = -ax/b -c/b

here slope is -a/b and y-intercept is -c/b

Add ( 2x^2 + 3xy +1) and (x^2 +4xy + 5)= (2x^2 + x^2) + (3xy+4xy) + (1+5)= 3x^2 + 7xy + 6
