Answer:

x=8.5, length is 17, and width is 6.5

Step-by-step explanation:

To solve for x, you would add the two sides together, getting x-2+2x+3x-2. Now, you would multiply this figure by two, because you only have half of the perimeter as of now. (3x-2)*2+6x-4. Now, because the perimeter is 47, you have this equation

6x-4=47

Add four to both sides

6x=51

Divide by 6

x=51/6=8.5

Now, you would plug this into both of the other sides of the rectangle.

The length, or the longest side, measures 2x

2*8.5=17

The width, or the shorter side, measures x-2

8.5-2=6.5

Hope this helped

Answer:

x = 8.5

L = 17

W = 6.5

Step-by-step explanation:

P = 2*(L + W)

W = x - 2

L = 2x

P = 47

47 = 2 * (2x + x - 2)

47 = 2 * (3x - 2)          Remove the brackets.

47 = 6x - 4                 Add 4 to both sides.

47 + 4 = 6x - 4+4       Combine

51 = 6x                       Divide by 6

6x/6=51/6                  Combine

x = 8 3/6 or 8.5

x = 8.5

========

L = 2*x

L = 2*8.5

L = 17

=====

W = x - 2

W = 8.5 - 2

W = 6.5

0.12x - 1.5= 0.24x - 0.06
Sophie [7]

To solve this equation, lets move all of the variables to one side of the equation and the constants to the other.

0.12x - 1.5 = 0.24x - 0.06

Subtract 0.12x from both sides of the equation

-1.5 = 0.12x - 0.06

Add 0.06 to both sides of the equation

-1.44 = 0.12x

Divide both sides by 0.12 to isolate x

x = -12

Use Heron's Formula to find the area of triangle ABC. Round your answer to the nearest whole number.
Scrat [10]

Step-by-step explanation:

use herons formula

√s(s-a)(s-b)(s-c)

where s is the semi perimeter

S=20

and a,b,c are sides of triangle

=√20(20-17)(20-9)(20-14)

=√20.3.11.6

=62.92

nearest whole number is 63

option B is correct
