Question

Let p(x) = (4x + 3)
2
and q(x) = (6x + 3)2
bet two polynomials. If Ram tells Sham that his age (in years)
is equal to the coefficient of x2
in polynomial p(x). Further he asserts that after two years his age (in
years) will be equal to half of the coefficient of x2
in polynomial q(x). ( 4 )
Based on above information answer any four following questions given below1) Age of Ram using polynomial p(x) is
a) 15 b) 20 c) 16 d) 45
2) Age of Ram after two years will be
a) 18 b) 20 c) 24 d) 27
Page-4/6
3) If age of Sham is one third of the coefficient of x in p(x) then his age is
a)5 c) 8 c) 10 d) 12
4) If age of Sham is one third of the coefficient of x in q(x) then his age is
a) 20 c) 16 c) 18 d) 12
5) Ratio of their ages as per question nos 2) & 4) is
a) 1 : 2 c) 3 : 1 c) 1 : 4 d) 1 : 1

Answer 1

Answer:

Economic recession is a period of general economic decline and is typically accompanied by a drop in the stock market, an increase in unemployment, and a decline in the housing market. Generally, a recession is less severe than a depression.

Answer 2

Step-by-step explanation:

The perimeter of field is 130

⟹AB+BC+CD+AD=130

AB=130−54−19−42

AB=15m

Area is given as

1/2

AB(AD+BC)1/2

×15(54+42)

15×48=720m
