Answer:

x = 2

Step-by-step explanation:

By the property of intersecting chords outside of the circle.

EC  \times ED = EB \times  EA \\ (x + 4)(x + 4 + 1) = (x + 1)(x + 1 + 11) \\ (x + 4)(x + 5) = (x + 1)(x + 12) \\  {x}^{2}  + (4 + 5)x + 20 =  {x}^{2}  + (1 + 12)x + 12 \\ 9x + 20 = 13x + 12 \\ 9x - 13x = 12 - 20 \\  - 4x =  - 8 \\ x =  \frac{ - 8}{ - 4}  \\  \huge \red{ \boxed{x = 2}}

Find the zeros of the polynomial x^2 + 8x + 16
Scorpion4ik [409]

hey mate,

x^2 + 8x + 16 = 0

<=>

(x+4)^2 = 0

As we know that (a+b)^2 = a^2+b^2+2ab

then

(x+4)^2 = 0

<=> (x+4) = 0

<=> x = -4

so there is one solution x = -4

thanks

Which expressions are equivalent to 4d+6+2d4d+6+2d ? Choose all answers that apply: Choose all answers that apply: (Choice A) A
Sliva [168]

Answer:

Options A and C are correct choices.

Step-by-step explanation:

We have been given an expression 4d+6+2d and we are asked to choose all the equivalent expressions from given choices.

Let us simplify our given expression.

4d+6+2d=(4d+2d)+6

4d+6+2d=6d+6

Let us see which of our given choices matches with our answer.

A. 2(3d+3)

Upon using distributive property a(b+c)=a*b+a*c we will get,

2*3d+2*3

6d+6

Therefore, option A is a correct choice.

B. 6(d+6)

Upon using distributive property a(b+c)=a*b+a*c we will get,

6*d+6*6

6d+36

Since this expression is not equivalent to our answer, therefore, option B is not a correct choice.

C. (3d+3)+(3d+3)

Upon removing parenthesis we will get,

3d+3+3d+3

Upon combining like terms we will get,

(3d+3d)+(3+3)

6d+6

Therefore, option C is the correct choice.
