3. y²+48-14y

4. a²+b²+c²+2ab-2bc-2ca

5. y³+64+12y²+48y

Step-by-step explanation:

1. (x-3)(y+5)

= xy+5x-3y-15

2. (y+9)(y-9)

= (y²-9²)

= y²-81

3. (y-7)²

= y²+48-14y

4. (a+b-c)²

= a²+b²+c²+2ab-2bc-2ca

Please solve the problem, and don't give unnecessary answer. Class 10 chapter Linear Inequation (ICSE)​

Answer»

\large\underline{\sf{Solution-}}

GIVEN inequality is

\rm :\longmapsto\:\dfrac{1}{<klux>2</klux>}  \leqslant x + 1 - \dfrac{x - 2}{2}  < 2\dfrac{1}{2}

\rm :\longmapsto\:\dfrac{1}{2}  \leqslant \dfrac{2x + 2 - (x - 2)}{2}  < \dfrac{5}{2}

\rm :\longmapsto\:\dfrac{1}{2}  \leqslant \dfrac{2x + 2 - x  + 2}{2}  < \dfrac{5}{2}

\rm :\longmapsto\:\dfrac{1}{2}  \leqslant \dfrac{x + 4}{2}  < \dfrac{5}{2}

On MULTIPLY by 2, each term we get

\rm :\longmapsto\:1 \leqslant x + 4 < 5

On Subtracting 4, from each term, we get

\rm :\longmapsto\:1 - 4 \leqslant x + 4 - 4 < 5 - 4

\rm :\longmapsto\: - 3\leqslant x  < 1

\bf\implies \:x \:  \in \: [ - 3, \: 1)

ADDITIONAL Information :-

\boxed{ \rm{ x > y\rm \implies\: - x <  - y}}

\boxed{ \rm{ x  <  y\rm \implies\: - x  >   - y}}

\boxed{ \rm{ x  <   - y\rm \implies\: - x  >    y}}

\boxed{ \rm{ x   >    - y\rm \implies\: - x   <     y}}

\boxed{ \rm{ x \geqslant y\rm \implies\: - x \leqslant  - y}}

\boxed{ \rm{ x \leqslant y\rm \implies\: - x \geqslant  - y}}

\boxed{ \rm{ x \leqslant  - y\rm \implies\: - x \geqslant  y}}

Answer:

(≧▽≦)(≧▽≦) (≧▽≦)(≧▽≦)

\csc( \sin( ln( \sec( \geqslant  \geqslant  \frac{ \sqrt[?]{?} }{?} ) ) ) )  \times \frac{?}{?}

The angle of elevation is when you are measuring the angle from the floor or the ground, and the angle of depression is when you are measuring from a ceiling. The only time the two angles are equal is if the ceiling and floor are parallel with each other.

  1. The angle of elevation is when you are measuring the angle from the floor or the ground, and the angle of depression is when you are measuring from a ceiling. The only time the two angles are equal is if the ceiling and floor are parallel with each other. If you know your angle terms these are opposite interior angles.
  2. If a ray is placed so that its endpoint is on a line and the ADJACENT angles are equal, then they are right angles
  3. Height is the measurement of an object in the VERTICAL direction and distance is the measurement of an object from a particular point in the HORIZONTAL direction. If we imagine a line connecting the point of observation to the topmost point of the object then the horizontal line, vertical line and the imaginary line will form a triangle.

Observe the figure. Consider the observer to be at point C. The height of the object is shown by line AB. The distance of the object from the observer is given by line BC. The object may or may not be PERPENDICULAR to the ground. Line AC REPRESENTS the Line of Sight when the observer is observing the topmost point of the object. Angle α represents the angle of elevation and Angle β represents the angle of depression

Quadratic Equations Exercise 5A – Selina Concise Mathematics Class 10 ICSE Solutions

Find which of the following equations are quadratic:

Solution 1(i)

(3x – 1)2 = 5(x + 8)

⇒ (9X2 – 6x + 1) = 5x + 40

⇒ 9x2 – 11x – 39 =0; which is of the form ax2 + bx + c = 0.

∴ Given equation is a quadratic equation.

Solution 1(ii)

5x2 – 8x = -3(7 – 2X)

⇒ 5x2 – 8x = 6x – 21

⇒ 5x2 – 14x + 21 =0; which is of the form ax2 + bx + c = 0.

∴ Given equation is a quadratic equation.

Solution 1(iii)

(x – 4)(3x + 1) = (3x – 1)(x +2)

⇒ 3x2 + x – 12x – 4 = 3x2 + 6x – x – 2

⇒ 16x + 2 =0; which is not of the form ax2 + bx + c = 0.

∴ Given equation is not a quadratic equation.

WhyQ1.A wire is in the shape of a square of side 10 cm. If the wire is rebent into a rectangle of length 13 cm, find its breadth. Which shape encloses more area?​

Answer»

Answer:

Let a be the SIDE of a square, l be the length and B be the BREADTH of rectangle.

As length of wire is constant, perimeter of both SHAPES would be same,

⇒4a=2(l+b)

⇒40=2(12+b)

⇒b=18 cm

Area of square=a

=10
