If (x + 8) is a factor of f(x), which of the following must be true?
Sedaia [141]

Answer:

  • f(-8) = 0

Step-by-step explanation:

If (x+8) is a factor of f(x), then for some expression p, we have ...

  f(x) = (x+8)p

Evaluated at x=-8, this gives ...

  f(-8) = (-8+8)p = 0p

  f(-8) = 0 . . . . must be true

_____

Similarly, f(8) = (8+8)p = 16p. This may or may not be zero, depending on the factors of p. The only offered statement that <em>must</em> be true is the one shown above.

Find the area of the rug. DO NOT ROUND.<br><br> what is the area?
Mademuasel [1]

Answer:

\frac{198}{7} \ \text{feet}^{2}

<h3>Step-by-step explanation:</h3>

<u>Given:</u>

  • Diameter of rug = 6 feet

To find the area of the rug, we need to use the formula "πr² or π(D/2)²"

<u>Where:</u>

  • r = radius
  • d = diameter

Since we do not have the radius, we need to substitute the diameter in the formula "π(D/2)²" to determine the area of the rug.

⇒ \pi (\frac{D}{2} )^{2}

⇒ \pi (\frac{6}{2} )^{2}

⇒ \pi (3 )^{2}

⇒ \pi (3 )(3)

⇒ 9\pi

Substituting "22/7" as π:

⇒ 9(\frac{22}{7} )

⇒ (\frac{198}{7} )

When finding the area of ANY shape, do not forget to include the units.

⇒ \frac{198}{7} \ \text{feet}^{2}
