Answer:

b. x² + 8x + 12 =

1. use the factoring X (see attachment)

2. 6 x 2 = 12; 6 + 2 = 12

3. (x + 6)(x + 2) = 0

4. x = -6, -2

c. x² + 13x + 12 =

1. 12 x 1 = 12; 12 + 1 = 13

2. (x + 12)(x + 1) = 0

3. x = -12, -1

c. x² + x - 12 =

1. 4 · (-3) = -12; 4 - 3 = 1

2. (x +4)(x - 3) = 0

3. x = -4, 3

f. x² + 15x + 36 =

1. 12 x 3 = 36; 12 + 3 = 15

2. (x + 12)(x + 3) = 0

3. x = -12, -3

hope this helps :)

Answer:

b) - (x + 2)(x + 6)

c) - (x + 12)(x + 1)

c) - (x - 3)(x + 4)

f) - (x + 12)(x + 3)

Step-by-step explanation:

Well to factor the given info we need to find the factors.

b)

x^2 + 8x + 12

So 6*2 = 12

6x + 2x = 8x

x*x = x^2

Factored - (x + 2)(x + 6)

c)

x^2 + 13x + 12

Well x*x = x^2

and 12*1 = 12

12x + x = 13x

Factored - (x + 12)(x + 1)

The second c)

x^2 + x - 12

Well x*x = x^2

-3*4 = -12

-3x + 4x = x

Factored - (x - 3)(x + 4)

f)

x^2 + 15x + 36

So x*x = x^2

12*3 = 36

12x + 3x = 15x

Factored - (x + 12)(x + 3)

<em />

<em>Thus,</em>

<em>everything factored is (x + 2)(x + 6) , (x + 12)(x + 1) , (x - 3)(x + 4) , </em>

<em>(x + 12)(x + 3).</em>

<em />

<em>Hope this helps :)</em>

Find the area of triangle jkl above if the vertices are j(2,2), k(3,5), and L(6,2)
tankabanditka [31]

Answer:

Area=6\:units^2

Step-by-step explanation:

Given the vertices (x_1,y_1)=J(2,2),  (x_2,y_2)=K(3,5) and

(x_3,y_3)=L(6,2). The area of triangle JKL is given by:

Area=\frac{1}{2}|x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y_2)|

We substitute the values to get:

Area=\frac{1}{2}|2(5-2)+3(2-2)+6(2-5)|

This simplifies to

Area=\frac{1}{2}|2(3)+3(0)+6(-3)|

Area=\frac{1}{2}|6+0-18|

Area=\frac{1}{2}|-12|

Area=\frac{1}{2}*12

Area=6\:units^2

A piece of wire in the form of a rectangle with the dimensions 12 m by 10 m is bent to form a circle . Find the diameter of the
irakobra [83]

Answer:

14.01m

Step-by-step explanation:

Perimeter of the rectangular wire = circumference of the circle

Perimeter of the rectangular wire = 2(L+W)

Perimeter if the rectangular wire = 2(12+10)

Perimeter if the rectangular wire = 2(22)

Perimeter if the rectangular wire = 44m²

Circumference of the circle = πd

44 = πd

d = 44/3.14

d = 14.01m

Hence the circumference of the circle is 14.01m
