Rewrite the function by completing the square. h(x)= x^{2} +3 x -18 left parenthesis, x, right parenthesis, equals, x, squared,

ludmilkaskok [199]

Answer:

h(x) = (x +1.5)^2 -20.25

Step-by-step explanation:

We assume you want to rearrange h(x)= x^2 +3x -18.

Recognize the coefficient of x is 3. Add and subtract the square of half that. (3/2)^2 = 9/4 = 2.25

h(x) = (x^2 +3x +2.25) -18 -2.25

Now, write the expression in parentheses as a square, simplify the constant.

h(x) = (x +1.5)^2 -20.25 . . . . . . . . vertex form

<u>To find the area of a complex shape</u>:

⇒ must split into simpler shapes

a rectangle of <u>8m by 7m</u>
a rectangle of <u>2m by 8 m</u>

<u>Now let's find</u>:

Area of a rectangle of <u>8m by 7m</u>

$Area=8*7=56m^2$

Area of a rectangle of <u>2m by 8m</u>

$Area = 2 * 8 = 16m^2$

<u>Total Area</u> = 56 + 16 = <u>72 m²</u>

<u>Answer: 72 m²</u>

Hope that helps!

2. Find the value of x. *<br> 3(x + 2)<br> RE<br> 24

Elan Coil [88]

Answer:

x=6

Step-by-step explanation:

3(x+2) = 24

Divide each side by 3

3/3(x+2) = 24/3

x+2 = 8

Subtract 2 from each side

x+2-2 = 8-2

x=6
