Consider the equation
.
It is easy to see that x=20 is a solution of this equation, because when x=20:
,
.
Also this equation have:
1. the variable on both sides;
2. a fractional coefficient on the left side;
3. a fraction on the right side.
Hello :
<span>(x+m)(x+n) =x² +mx +nx +mn
</span><span>a trinomial is factored as (x+m)(x+n) is : x² +(m+n)x +mn
</span>
<span>A. The degree of the trinomial : 2
B. The constant term of the trinomial : mb
C. The coefficient of the x-term of the trinomial : m+n
D. The coefficient of the x^2-term of the trinomial : 1</span>
To get the area of the cone we need to find the radius first.
tan 70=r/12
r=12tan 70
area of a circle is given by:
A=πr²
thus the area of the ground covered by the tent will be:
A=π(12tan70)²
The answer is
A] A=π(12tan70°)²
