Find x segments of circles

Mathematics
1 answer:
DerKrebs [107]3 years ago
7 0

Answer:

x = -9

x = 2

Step-by-step explanation:

We can say that:

x (x + 7) = 6*3

x² + 7x = 18

x² + 7x - 18 = 0

Now solving by quadratic formula we get;

x = 2, and -9

if we substitute in -9 for x, let's see what happens:

(-9) (-9 + 7) = 6*3

(-9) (-2) = 6*3

18 = 18

therefore x = -9 works! Let's see what happens if we substitute x in for 2;

(2) (2 + 7) = 6*3

(2) (9) = 6*3

18 = 18

Therefore x = 2 works as well!

<u>The final answer would be;</u>

<u>x = -9</u>

<u>x = 2</u>

Hope this helps!

lilavasa [31]

Answer:

P(x)=(x+9)(x^2-7x+52)+3

Step-by-step explanation:

We are given that

P(x)=x^3+2x^2-11x+471

d(x)=x+9

We have to find the value of Q(x) and Remainder R(x).

Quotient, Q(x)=x^2-7x+52

Remainder,R(x)=3

We know that

Dividend=Divisor\times Quotient+Remainder

P(x)=(x+9)(x^2-7x+52)+3

Answer:

  4. True

  5. False

Step-by-step explanation:

4. The number of x-intercepts produced by the quadratic formula may be 0, 1, or 2. It will be 0 if the two roots are complex. It will be 1 if the two roots lie in the same place (one root with multiplicity 2). It is true that there may be only one x-intercept.

__

5. The value of 'b' in the quadratic formula is the coefficient of the linear term. In the given quadratic, it is -5, not 5.
