Step-by-step EXPLANATION:

y2 + 3√5/2y - 5 = 0

2y2 + 3√5y - 10 = 0

2y2 + (4√5y - √5y) - 10 = 0

2y2 + (4√5y - √5y) - 10 = 0

2y(y + 2√5) - √5(y + 2√5) = 0

(y + 2√5)(2y - √5) = 0

⇒ y = - 2√5, √5/2

Verification:

Sum of the zeroes = - (coefficient of X) ÷ coefficient of x2

α + β = - b/a

(- 2√5) + (√5/2) = - (3√5)/2

= - 3√5/2 = - 3√5/2

Product of the zeroes = constant term ÷ coefficient of x2

α β = c/a

(- 2√5)(√5/2) = - 5

- 5 = - 5

3(-1)² = 3

ANSWER:

answer is EASY but METHOD is HARD

Answer:

4.71 is the MEAN of the FOLLOWING

Given

Perimeter of Rectangle is 90 units .

LENGTH is 3 more than the WIDTH.

To Find

we have to find the length

Since, perimeter of Rectangle is given and we don't know the length and breadth.So,let us assume the length and breadth some Variable.

Let the breadth be 'x'

Length is 3 more than the width :

Then our Equation BECOMES :3+x

Perimeter of Rectangle= 2(l+b)

Where ,l is the length and b is the breadth

=> Perimeter of Rectangle= 2(3+x+x)

=> 90= 2(2x+3)

=>90= 4x+6

=> 84= 4x

=> x= 84÷4

x= 21

Hence, breadth is 21 units

length = 3+x= 3+21= 24 units

Check:

Perimeter of Rectangle= 2(24+21)

Perimeter of Rectangle=2(45)=90 units.

Extra information=>

Perimeter is the TOTAL distance occupy by a solid 2D figure around its edge.

Some properties of Rectangle:

• Opposite sides are EQUAL and parallel
• Both Diagonals bisects each other and are equal in length.
• The sum of all Interior angles is 360°.

7√6 - √252 - √294 + 6√7

==>. 7√6 - √( 6 × 6× 7) - √( 7 ×7 ×6) + 6√7

==>. 7√6 - 6√7 - 7√6 + 6 √7

==> 7√6 - 7√6 - 6√7 + 6√7

==> 0

3X + 2 = 88 - 8

3x + 2 = 80

x = (80 - 2)/3

= 78/3

= 26

so the VALUE of X is 26
