Answer:

D. ( {x} - 2)^{2}  = 7

Step-by-step explanation:

3 {x}^{2}  - 12x = 9 \\ 3( {x}^{2}  - 4x) = 9 \\  {x}^{2}  - 4 x= 3 \\  {x}^{2}  - 4x + 4 = 3 + 4 \\  {x}^{2}  - 4x +  {2}^{2}  = 7 \\ ( {x} - 2)^{2}  = 7

Help me using the image below
ZanzabumX [31]

Answer:

The value of x is 105°

Step-by-step explanation:

Firstly, you have to find the total angles in regular hexagon and octagon using the θ = (n-2)×180° where "n" determine numbers of edges :

hexagon,

θ = (6-2)×180°

= 4 × 180°

= 720° (total angles)

octagon,

θ = (8-2)×180°

= 6 × 180°

= 1080° (total angles)

Then, calcular the angle for each edge :

hexagon,

θ = 720° ÷ 6

= 120°

octagon,

θ = 1080 ÷ 8

= 135°

Lastly, to find the value of angle x. As the angle in a circle is 360° so you have to substract :

x = 360° - 135° - 120°

= 105°

What is the product of (x-3) and (x + 7)?
saul85 [17]

Answer:

The answer is D: x (Squared) + 4x - 21.

Step-by-step explanation:

(X-3)(x+7)

First you multiply the first x by x, to get x squared. Then you multiply the first x by 7 to get 7x.

Next you multiply the -3 by the second x, to get -3x. Then you multiply the -3 by the 7 to get -21.

Written in order it would look like:

X (squared) + 7x -3x -21

You can combine the 7x and the -3x because they are like terms. This would leave you with:

x (squared) + 4x - 21
