A = 7 as 7 + 5 = 12. We want 2 at units place and 1 is carry over. Now 3 + 2 + 1 = 6
B = 6
Hence A = 7 and B = 6

If the value of a variable x always increases or decreases with the respective increase or decrease in value of variable y, then it is said that the variables x and y are in direct proportion.
For example : In the table below, we have variable y – Cost (in Rs) always increasing when there is an increase in variable x – Weight of sugar (in kg). Likewise if the weight of sugar reduced, the cost would also reduce. Hence the two variables are in direct proportion.

False
A rectangle is a quadrilateral with all four angles right angles.
From this definition, you can prove that the opposite sides are parallel and of the same lengths. A rectangle can be tall and thin, short and fat or all the sides can have the same length.
Definition: A square is a quadrilateral with all four angles right angles and all four sides of the same length.
So a square is a special kind of rectangle, it is one where all the sides have the same length. Thus every square is a rectangle because it is a quadrilateral with all four angles right angles. However not every rectangle is a square, to be a square its sides must have the same length.l

Given:-
Volume of the cylinder = 1.54m³
Diametre of the base = 140cm
Radius of the base = 140/2
= 70cm
= 0.7m
Volume of cylinder = πr²h
1.54 = 22/7*0.7²*h
1.54*7/22*0.7*0.7 = h
h = 1
Height = 1m Ans.
Ans.) The height of the cylinder is 1m.

Example:
Add 5xy – 3x2 – 12y +5x, xy – 3x – 12yz +5x3 and y – 6x2 – zy +5x3
Solution:
For adding these three algebraic expressions the like terms are grouped together and added as shown below.

Arrange the terms of the given expressions in the same order.
Subtraction of Algebraic Expressions
For subtracting two or more algebraic expressions, it’s a better practice to write the expressions to be subtracted below the expression from which it is to be subtracted from. Like terms are placed below each other. The sign of each term which is to be subtracted is reversed and then the resulting expression is added normally.
Example:
Subtract x2y –2x2 -zy + 5 and –3x2 +3x3 from y3 +3x2y –6x2 -6zy +7x3
Solution:
The like terms of the expressions x2y – 2x2 – zy + 5 and – 3x2 + 3x3 are written below the like terms of the expression y3 +3x2y – 6x2 – 6zy + 7x3.

For adding two or more algebraic expression the like terms of both the expressions are grouped together. The coefficients of like terms are added together using simple addition techniques and the variable which is common is retained as it is. The, unlike terms, are retained as it is and the result obtained is the addition of two or more algebraic expressions.
Example:
Add 5xy – 3x2 – 12y +5x, xy – 3x – 12yz +5x3 and y – 6x2 – zy +5x3
Solution:

RBCs are the biconcave cells and without nucleus in humans; also known as erythrocytes. RBCs contain the iron-rich protein called haemoglobin; give blood its red colour. RBCs are the most copious blood cell produced in bone marrows. Their main function is to transport oxygen from and to various tissues and organs.
Leucocytes are the colourless blood cells. They are colourless because it is devoid of haemoglobin. They are further classified as granulocytes and agranulocytes. WBCs mainly contribute to immunity and defence mechanism.
Following are the important functions of the nuclear membrane:
- The nuclear envelope has tiny holes which are identified as nuclear pores. The pores enable the content to flow in and out of the nucleus. It also connects the outer membrane and the inner membrane.
- The nuclear envelope’s surface area extends and doubles the nuclear pores during the interphase part of cell division.
- Nuclear membrane shields the nucleus with a double membrane by many pores that help in controlling the crossing of macromolecules such as proteins and RNA and permit free passage of water, ions, ATP and small molecules. The membrane controls the flow of information in the cell as it is conducted by the macromolecules.
