Answer:

C. g(x) = -2 \cdot (x + 1)\cdot (x+7)

Step-by-step explanation:

The polynomial form that reveals most quickly the zeroes is the form of a product of binomials. That is:

g(x) = \Pi\limits_{i=1}^{n}  (x-r_{i})

Where \Pi is the product function and r_{i} is the i-th root of the polynomial.

Hence, g(x) = -2 \cdot (x + 1)\cdot (x+7) resembles a form that is close to the form described above. The right option is C.

Find the area of the shaded region. The radius of the large circle is 10 m. Round answer to the nearest hundredth.
vivado [14]

Answer:

hello the figure related to your question is missing attached below is the missing figure

answer : 157.08 m^2

Step-by-step explanation:

Calculate the area of the shaded area

= Area of the large circle - Areas of the small circles

= (( \frac{\pi }{4} ) * D^2) - 2(  ( \frac{\pi }{4} ) * d^2 )     given that the small circles are congruent

= (( \frac{\pi }{4} ) * 20^2 ) - 2 ( ( \frac{\pi }{4} ) * 10^2 )

= 314.16 - 157.08

= 157.08 m^2

What is the factored form of 8x2 + 12x? 4(4x2 + 8x) 4x(2x + 3) 8x(x + 4) 8x(x2 + 4)
earnstyle [38]
So I'm guessing that the x2 is your way of saying 2 is the exponent right? In that case the equation would be 8x^2 + 12x
Well you would have to pull out the gcf which in this case will be 4x after pulling out the gcf you should get 4x(2x + 3)
