Question

(1) Use the given letters to write the answer.
(1) There are 'a' trees in the village Lat. If the number of trees increases every year
by 'b', then how many trees will there be after 'x' years?
(ii) For the parade there are y students in each row and x such row are formed. Then,
how many students are there for the parade in all ?
(iii) The tens and units place of a two digit number is m and n respectively. Write
the polynomial which represents the two digit number.​

Answer 1

Answer:

(1). Total number tree in x years is a + bx.

(2). Total number of students = (x)(y)

(3).m(10) +n(1) is the polynomial of the two digit number.

Step-by-step explanation:

(1). Number of trees in the village Lat is = a

    Number of trees increases every year  = b

    Number of years = x

Let us consider the number of tree in 2 year = 2 x ( Number of trees increases every year)= 2x b = 2b

similarly, the number of trees in 3 year = 3b

consequently , the number of trees in x years = bx

we already know that,

Number of trees in the village Lat is 'a'

therefore,

By the end of x years the total number of tree in the village Lat = a + bx

Total number tree in x years =  a + bx.

(2). Number of students in each row = y

     Number of students in each column = x

    Total number of students in parade = (Number of students in each row) x

(Number of students in each column)

     = (x)(y)

Total number of students = (x)(y)

(3). The tens place = m

the value of the tens place = m x 10

The units place = n

the value of the units place = n x 1

Polynomial of the two digit number is equal to = m(10) +n(1)

Therefore,

m(10) +n(1) is the polynomial of the two digit number.
