Complete the square to transform the expression x^2+4x 2 into the form a(x − h)2 + k.

faust18 [17]

Answer:

$(x+2)^2-2$

Step-by-step explanation:

we have the expression

$x^2+4x+2$

Convert to vertex form

$a(x-h)^2+k$

where

a is the leading coefficient

(h,k) is the vertex

Complete the square

$(x^2+4x+2^2)+2-2^2$

$(x^2+4x+2^2)-2$

Rewrite as perfect squares

$(x+2)^2-2$

The coefficient a =1

The vertex is the point (-2,-2)

Answer:

See step-by-step explanation

Step-by-step explanation:

16. C, <AOB = 20

The total angle (<AOC) is equal to the sum of the angles inside of it (<AOB and < BOC).

<AOC= <AOB + <BOC

47=<AOB+27

<AOB=20

17. 24

Area of a square = $s^{2}$

36= $s^{2}$

s= 6

One side is 6

The perimeter of a square is 4(s)

4(6) = 24

Word of encouragement:

Good luck!
