These three measurements of sides and angles to draw a unique triangle. This makes the student understand better and give them an option to choose the solution more suitable to them. Besides, students can bring in all their queries regarding maths as well as other subjects including physics, chemistry, and biology. See the other Exercises like or or or or Solutions. Go back to main page or move to of the page. Video Solution Answer: Let the larger and smaller number be x and y respectively.

See the other Exercises like or or or or Solutions. Hence, the given equation is not a quadratic equation. As vertex R is 4. The Central Board of Secondary Education is one of the popular educational board in India. We can get cubes of numbers by adding consecutive odd numbers pattern. Therefore, while taking E and T as centres, draw arcs of 4. Hence, the given equation is a quadratic equation.

Standard identities and their uses in solving algebraic expressions. Video Solution Answer: Let the sides of the two squares be x m and y m. We need to find the integers. The solution is thus checked for its correctness. Additive identity 0 and the multiplicative identity 1. Answer: i 1 A rough sketch of this quadrilateral can be drawn as follows. Go back to main page or move to of the page.

These will be intersecting each other at point R. Thus providing an insight of the marking scheme to students for a high score. These will intersect each other at point M. Answer: Let the number of articles produced be x. Square root is the inverse operation of square.

It was observed on a particular day that the cost of production of each article in rupees was 3 more than twice the number of articles produced on that day. Comparing simple interest and compound interest on the same amount. See the other Exercises like or or or or Solutions. See the other Exercises like or or or or Solutions. As the vertices, A and Y, are 4. Terms are added to form algebraic expression and these terms themselves can be formed as the product of factors. A diagonal is a line segment connecting two non-consecutive vertices of a polygon.

If the total cost of production on that day was Rs 90, find the number of articles produced and the cost of each article. As vertex A is 6. In this chapter you will find Vise Chapter and you can easily get this book from star. Therefore, while taking D and L as centres, draw arcs of 10 cm radius and 7. Therefore, while taking 0 and E as centres, draw arcs of 4.

Refer to our Textbook Solutions any time, while doing your homework or while preparing for the exam. Division of algebraic expression — monomial by another monomial, polynomial by monomial and polynomial by polynomial. These will be intersecting each other at point R. Treatment of additional expense during the purchase of an article. Answer: i A rough sketch of this quadrilateral can be drawn as follows. Hence, the given equation is a quadratic equation. However, length cannot be negative.

Question 3: Draw the rectangle according to the given information. However, age cannot be negative. Answer: i Let the breadth of the plot be x m. As vertex A is 6. These will intersect each other at point M. We need to find the length and breadth of the plot. Register for our free webinar class with best mathematics tutor in India.

It is given that their product is 306. Let this ray meet the previously drawn ray from R at point E. For example cubes, cuboids, cones, cylinders, spheres, hemispheres, etc. Types of polygon — Triangle, quadrilateral, pentagon, hexagon. Let the point of intersection be M.
