Simplify x^2+6x+8/x+2

Mathematics
1 answer:
Lady_Fox [76]3 years ago
3 0

Answer:

(x + 4)

Step-by-step explanation:

\frac{ {x}^{2}  + 6x + 8}{x + 2}  \\  \frac{ {x}^{2}  + 4x + 2x + 8}{x + 2}  \\  \frac{ x(x + 4) + 2(x + 4) }{(x + 2)}  \\  \frac{(x + 2)(x + 4)}{(x + 2)}  \\  = ( x+ 4)

Hope this helps you.

Let me know if you have any other questions :-)

Two poles, AB and ED, are fixed to the ground with the help of ropes AC and EC, as shown:
kipiarov [429]

Answer:

15.59 feet

Step-by-step explanation:

We need to find BC and CD

First find BC

We can use the Pythagorean theorem

AB^2 + BC^2 = AC^2

11^2 + BC^2 = 13^2

121 + BC^2 =169

Subtract 121 from each side

121-121+BC^2 = 169-121

BC^2 = 48

Take the square of each side

sqrt(BC^2 ) = sqrt( 48)

BC = 6.92820323

then we need to find CD

We can use the Pythagorean theorem

CD^2 + DE^2 = CE^2

CD^2 + 5^2 = 10^2

CD^2 + 25 =100

Subtract 25 from each side

CD^2 + 25-25 =100-25

CD^2 = 75

Take the square of each side

sqrt(CD^2 ) = sqrt( 75)

BC = 8.660254038


BD = BC +CD

     = 6.92820323 + 8.660254038

     15.58845727

Please help asap! really important!!
Alexxandr [17]

Answer:

4th graph

6th graph

3rd graph

Step-by-step explanation:

Linear = y = x + 3

it is 4th graph

when you substitute x = 0 y is 3

and when y = 0 x is -3

Quadratic = y = 3x^2

It is 6th graph

for both positive and negative values of x, y is rapidly increasing

Exponential = y = 3^x

it is 3rd graph

for x = 0 y value is 1 because 3^0 = 1

for positive values of x, y is exponentially rising

for negative values of x it is nearly almost touches zero

The ratio of men to women in a room is 3:4. Eight women enter the room, no men enter the room and none of the original people in
vampirchik [111]
There are 64 people in the room.

Since the ratio for women increases 1 when 8 women enter the room, for every time there is 1 in the ratio there are 8 people. That means that originally you have to do 3x8 and 4x8. You get 24 and 32 which equals 56. Then when 8 more women enter the room, you get 64.
