Zero of 7 with a multiplicity of 3 means one factor is $(x-7)^3$

Zero of -1 with a multiplicity of 2 means one factor is $(x+1)^2$

Zero of 5 with a multiplicity of 1 means one factor is $(x-5)$

Multiplying, we get

$f(x) = (x-7)^3(x+1)^2(x-5)$

That's already in factored form so we leave it here.

Which is the first step in simplifying the expression?

Elenna [48]

$\dfrac{3}{2 + \sqrt{2} }$

To rationalise the denominator, this is a standard step:
$= \dfrac{3}{2 + \sqrt{2} } \times \dfrac{2 - \sqrt{2}}{2 - \sqrt{2}}$

Answer: Option A

---------------------------------------------------------------------------------------------------

Let me continue to complete the question, though it is not ask for

$= \dfrac{3(2 - \sqrt{2})}{(2 + \sqrt{2)}(2 - \sqrt{2}) }$

$= \dfrac{3(2 - \sqrt{2})}{4 - 2 }$

$= \dfrac{6 - 2\sqrt{2}}{2 }$

the coordinates (1,1), (7,3), (8,0) and (2,-2) are joined which shape is formed as Square

When the coordinates (1,1), (7,3), (8,0) and (2,-2) are joined, a square is formed. The sides are equal length and the angles are all 90 degrees.The coordinates (1,1), (7,3), (8,0) and (2,-2) are points on a two-dimensional plane. When the points are connected, a square is formed. A square is a four sided shape with four 90 degree angles and four equal length sides. The length of each side can be calculated by finding the distance between the two points. For example, the distance between (1,1) and (7,3) is 6 units. Therefore, the length of each side of the square is 6 units.

Answer:

To do this, subtract 6 from both sides. − 3_x_ + 6 − 6 > 12 − 6. −3_x_ > 6. Now divide both sides of the inequality by −3. Since you're dividing by a negative number, you need to flip the inequality sign.

11. Write 343 with an exponent by using<br> 7 as the base.

dimulka [17.4K]

Answer:

343 can be written as

$7 {}^{3}$

Step-by-step explanation:

since we know,

343 = 7 × 7 × 7

so, we can write 343 as cube of 7

hence,

$343 = 7 {}^{3}$
