38cm

Step-by-step explanation:

The perimeter of the quadrilateral

ABCD=AB+BC+DC+AD.

From the question,

AB =9cm, BC=12cm and DC=4cm.

This implies that we need to find the length AD before we can proceed to find the perimeter.

From the diagram, we can find |AD| using Pythagorean Theorem.

[tex]{|AD|}^{2} = {12}^{2} +{5}^{2}[/tex]

[tex]{|AD|}^{2} =144+ 25[/tex]

[tex]{|AD|}^{2} =169[/tex]

Taking positive square root of both sides

[tex]|AD|= \sqrt{169}[/tex]

[tex]|AD|=13 \: cm[/tex]

Hence the perimeter

=9+12+4+13

=38cm

7 1/2 feet

Step-by-step explanation:

Area of the Mural painted wall = 112 1/2 sq.feet = 225/2 sq.feet

width * length = 225/2

15 * length = 225/2

[tex]length=\frac{225}{2*15}\\=\frac{15}{2}\\\\=7\frac{1}{2}[/tex]

b is not a linear function

Step-by-step explanation:

any equation with an x∧2 is not a linear function they produce a curved line.

f(-1)= 1 and 9

f(0)= 8 and 16

f(2)= 21 and 30

Step-by-step explanation:

Hey there!

We have the absolute value of x is greater than two.

Thus, to solve absolute value inequalities, we want to break the inequality down.

We break this down to

x>2

x<-2

Thus, we don't need to simplify this any further, and have our answer.

Hope this helps :)

Explanation:

all i know for the first part

Step-by-step explanation:

6x - 12 + 3x + 30 = 90

9x + 18 = 90

9x = 72

x = 8

6(8) - 12 = 48 - 12 = 36 for m<AOB

3(8) + 30 = 24 + 30 = 54

x >= 2 or x <= -2

Step-by-step explanation:

|x|>= 2

Means the absolute value of x is greater than or equal to two.

When we deal with absolute value, we can equivalently break into two cases

+x >= 2    => x >= 2

-x >= 2    =>  x <= -2

On the number line it looks like what is shown in the attached figure.

x = -1/5y +3

Step-by-step explanation:

add -y to both sides

5x + y + -y = 15 + -y

5x = -y + 15

step 2 divide both sides by 5

5x/5 = -y +15/5

x= -1/5 y +3

Answer

x= -1/5 y + 3
