Answer:
(B , D) = (-2,5)
Step-by-step explanation:
The given quadratic expression is
compare the given expression with
so we have
now and
we need to find two numbers such that their product is -30 and sum is -1
-6 and 5 are such numbers
grouping first two terms and last two terms
factor out 3x from first two terms and 5 from last two terms
( factor out (x-2))
hence B =-2 and D= 5
(B,D)= (-2,5)
0.381mm or 0.015in
no. of papers in the stack-700
total length of stack-10.5in
thickness of single piece of paper= 10.5/700= 0.015in=0.381mm
5 times 2 plus 3 plus 2 times 4
4y+2/(x-y)(x+y)
