Equation  x^2+4x+2 is converted to  1(x-(-2))^2-2

<u>Step-by-step explanation:</u>

We need to complete the square to transform the expression x^2+4x+2 into the form a(x-h)^2+k . Let's do this :

We have , following equation to convert as :

⇒ x^2+4x+2

⇒ (x+2)^2-2

⇒ 1(x+2)^2-2

⇒ 1(x+2)^2-2

⇒ 1(x-(-2))^2-2

Comparing this to equation  a(x-h)^2+k we get :

a=1\\h=-2\\k=-2

Therefore , Equation  x^2+4x+2 is converted to  1(x-(-2))^2-2.

An office manager needs to decide between two tables for the conference room. One is rectangular, 5 feet wide by 10 feet long. T
7nadin3 [17]

Answer:

The rectangular 5 x 10 table.

Step-by-step explanation:

To find which table the office manager needs to get so he can sit more people at it is decided by one factor, the perimeter. The rectangular one, which is 5 x 10 the perimeter is (5 x 2) + (10 x 2) = 10 + 20 = 30. The circular one can be calculated by the equation\pi * d where d = 8. Putting /pi x 8 in my calculator and it comes out approximately at 25.132, having a less amount of perimeter space to work with, making the rectangular table the way to go.

Help and explain ///////////////////////////
Ilia_Sergeevich [38]

Hello,

First, you must understand that

(f-g)(x) means f(x)-g(x) it is the difference of two functions :

f(x)=2x+4 and g(x)=3x-7

f(5)=2*5+4=10+4=14

g(5)=3*5-7=15-7=8

So, (f-g)(5)= f(5)-g(5)=14-8<u>=6</u>

Answer A: none of the choices are correct.

An other way to do it:

(f-g)(x)=f(x)-g(x)=2x+4-(3x-7)= 2x-3x+4+7=-x+11

if x= 5 then (f-g)(5)=-5+11<u>=6</u>
