In the library, there are 12x English books, 5x Chinese books and 4x Malay books. If there are 15 fewer Indian books than Malay books, find the to
number of books in the library in terms of x.

25x - 15

Step-by-step explanation:

Indian books = malay books - 15

=4x -15

Total books =

English books + chinese books + malay + indian

= 12x + 5x + 4x + 4x -15

= 25x - 15

Step-by-step explanation:

Indian books = 4x - 15

Total books = 12x + 5x + 4x + 4x - 15  {add like terms}

                     = 25x - 15

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
