QUESTION: 4

The answer of factorization of the expression 4z(3a + 2b - 4c) + (3a + 2b - 4c) is

Solution:

Consider (3a+2b-4c)=A
=> 4zA+1A
=> (4z+1)A
=> (4z+1)(3a+2b-4c)

Solution:
QUESTION: 7

The _______ of the variable in an equation which satisfies the equation is called a solution to the equation.

Solution:

The value of the variable in an equation which satisfies the equation is called a Solution to the Equation. So for example we take the equation 2n=10, If n = 1, the number of matchsticks is 2. Clearly, the condition is not satisfied, because 2 is not 10.

QUESTION: 8

The ________ of an equation is equal to its RHS only for a definite value of the variable in the equation.

Solution:
QUESTION: 9

Solution:
QUESTION: 15

What is an expression for the statement: “p is multiplied by 16”?

Solution:

The correct option is Option A.

If we break the factor 16p, it can be written as p multiplied with 16 (16 × p)

If we break the factor 16 - p, it can be written as p subtracted from 16 (16 - p)

If we break the factor 16 + p, it can be written as p added to 16 (16 + p) 

QUESTION: 16

Perimeter of an __________ = 3 × length of a side

Solution:
QUESTION: 17

Pick out the solution from the values given in the bracket next to each equation. p – 5 = 5 (0, 10, 5 – 5)
