The width of deck= x = 7 feet when perimeter is 48 feet and length is 17 feet
Step-by-step explanation:
Let width of rectangle = x
Let length of rectangle =3+2x
Perimeter of Rectangle = 48 feet
Width of rectangle = ?
The formula of perimeter is:

Putting values of perimeter, length and width

So, the width of deck= x = 7
The length will be= 3+2x = 3+2(7) = 3+14 = 17

2.(x - 3) - 5 = 4.(x + 3) - 2x
2x - 6 - 5 = 4x + 12 - 2x
2x - 4x + 2x = 12 + 6 + 5
4x - 4x = 23
0 = 23
Something is wrong, you must have wrote something wrong
( 5.3 * 10^4 ) ( 4.2*10^3)
Multiply the numbers and add the exponents
(5.3 * 4.2) * 10 ^ (4+3)
22.26 * 10^7
now we have to adjust since more than 1 number is in front of the decimal
2.26 * 10^(7+1)
2.26*10^8
Answer:
x=1/3
Step-by-step explanation:
3x-1=1-3x
<u>-3x -3x</u>
-1=1-6x
<u>-1 -1</u>
<u>-2</u>=<u>-6x</u>
-3 -3
1/3=x
