Answer:
(7x-1)-3(7x-1)
Step-by-step explanation:
First write out the problem
7x^2-22x+3
Next, Factor the expressions
7x^2 - x - 21x + 3
Now factor the whole thing
x(7x-1)-3(7x-1)
Answer:
x = 28°
Step-by-step explanation:
Take angle on a straight line which is equal to 180°
180° =(108 + 44 + x)°
180° = 152° + x°
180° - 152° = x°
28° = x
Answer:
Change in sulfur oxide in the air =
Step-by-step explanation:
Data provided in the question:
Relation between the amount of sulfur oxide in the air and the population as:
S² = 110P² + 20P + 600
Population growth rate, = 10 people per month
Now,
change in sulfur oxide with time i.e
differentiating the given relation with respect to time 't'
we have
= + 20
at P = 100 and = 10 people per month
we have
= 2 × 110 × 100 × 10 + 20
or
= 220020
or
=
or
Change in sulfur oxide in the air =
Step-by-step explanation::20x-10x=10x(2-1)=10x
