As points, x-intercepts take the form
, so to find the intercepts we can set
and solve for
.
From the first equation alone, we already know that
is a solution, which means one intercept is
.
The second equation gives
so that the second intercept occurs at
.
So if
and
, we have
, giving C as the answer.
Formula for the area of a circle is Pi*radius squared
So, we do Pi*2^2 which is 12.57
Answer:
105 sq. cm
Step-by-step explanation:
The shortest altitude will ⊥ to the longest side.
A = (1/2)bh
=.5(30)(7)
= 105 sq. cm

Step-by-step explanation:
<h2><u><em>Lesson: Zero and Negative Exponents</em></u></h2><h2>Zero exponent rule:
</h2>
First, you multiply by exponents.
It change positive to negative sign.
<u><em>Final answer is B. -16</em></u>
Hope this helps!
Have a nice day! :)

x^2 - 14x - 32 = x^2 - 16x + 2x - 32 = x(x-16) + 2(x-16) = (x - 16)(x + 2)
<h2>
⇒ x^2 - 14x - 32 = (x - 16)(x + 2)</h2>
