Answer:
60
Step-by-step explanation:
given:
l = 10
b = 5
h = 2
to find:
2h(l + b)
substitute the given values of l , b and h
=2*2(10 + 5)
=4*15
=60
Let's find at first
Let's find (a+b)(a-b)....
we should divide both side of fraction by b and we will get the following:
and (a-b)/(a+b) is same as (1/[(a+b)/(a-b)]) so we can use previous answer and finally we will have (a-b)/(a+b) = 1/[ (tanx + 1) / (tanx - 1)] = (tanx - 1)/(tanx + 1) and final answer will be this:

Answer:
Step-by-step explanation:
f(x)=(x-6)(x-2)(x+3)
=(x-6)(x^2+x-6)
=x^3+x^2-6x-6x^2-6x+36
or f(x)=x^3-5x^2-12x+36
