The area of the pentagon is 5(1/2*9*13) = 5(58.5) = 292.5 square units.

There are 2 pentagons, so the area of the two are: 292.5 x 2 = 585 square units.

The area of the rectangle is 20 * 13 = 260 square units.


Total area = 260 + 585 = 845 square units.


The answer is D.

Y = x + 3<br> 4x + y = 18
Drupady [299]

Answer:

x=3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4x+x+3=18

(4x+x)+(3)=18(Combine Like Terms)

5x+3=18

5x+3=18

Step 2: Subtract 3 from both sides.

5x+3−3=18−3

5x=15

Step 3: Divide both sides by 5.

5x/5 = 15/5

x=3

2 * 4 = 8

8 < 11 is true

2 * 5 = 10

10 < 11 is true

2 * 5.3 =  10.6

10.6 < 11 is true

2 * 5.7 = 11.4

11.4 < 11 is NOT true.

x = 5.7 is not a solution.

HELP ME ON THIS PLEASE!!!! SHOW WORK!!!!
Mumz [18]

Answer:

<h2>1. x = 4</h2><h2>2. x = 20</h2>

Step-by-step explanation:

1.

ΔABC and ΔAJK are similar (AA). Therefore the sides are in proportion:

\dfrac{AC}{AJ}=\dfrac{AB}{AK}

We have:

AC = 1 + 4 = 5

AJ = 1

AB = 1 + x

AK = 1

Substitute:

\dfrac{5}{1}=\dfrac{1+x}{1}

5=1+x           <em>subtract 1 from both sides</em>

4=x\to x=4

2.

ΔVUT and ΔVMN are similar (AA). Therefore the sides are in proportion:

\dfrac{VU}{VM}=\dfrac{VT}{VN}

We hve:

VU = x + 8

VM = x

VT = 49

VN = 49 - 14 = 35

Substitute:

\dfrac{x+8}{x}=\dfrac{49}{35}              <em>cross multiply</em>

35(x+8)=49x          <em>use the distributive property a(c + b) = ab + ac</em>

35x+280=49x              <em>subtract 35x from both sides</em>

280=14x         <em>divide both sides by 14</em>

20=x\to x=20
