Answer:
Step-by-step explanation:
Solution
I'm assuming you want this simplified. If not leave a note.
a(x + 1) - b(x + 1) - x - 1 remove the brackets
ax + a - bx - b - x - 1 gather like terms
ax - bx - x + a - b - 1
x(a - b - 1) + (a - b - 1) Use the distributive property to simplify
Answer
(x + 1)(a - b - 1)
The common factor is (a - b - 1). That can be pulled out on either side of the isolated + sign
Percent formula : is / of = % / 100
12 is ? % of 200..
is = 12
of = 200
% = x
now sub and solve
12/200 = x / 100
cross multiply because this is a proportion
(200)(x) = (12)(100)
200x = 1200
x = 1200/200
x = 6.......so 12 is 6% of 200 <==
Answer:
12
Step-by-step explanation:
The formula to find the area of a circle is:


Where "r" is the radius of the circle.
In this case, the radius is 2, and as per what is given in this problem (what the problem asks one to use), pi is rounded down to 3.
The equation will be:
3 * 2^2
Simplify, remember the order of operations:
3 * 4
