Answer:
width = 15 inches
length = 36 inches
Step-by-step explanation:
To solve you need to find the width...
width = w
length = 2w + 6
the perimeter is all the way around the area, so..
2w + 2(2w + 6) = 102
because there are 2 widths and 2 lengths in a perimeter.
Solve for w:
2w + 4w + 12 = 102
subtract 12 from both sides and combine like terms...
6w = 90
divide both sides by 6...
w = 15
the width = 15, and the length = 2(15) + 6 = 36
-6x -(3x)
Pretend that there is a -1 in front of the bracket
-6x-1(3x)
mutiply the bracket by -1
(-1)(3x)= -3x
-6x-3x= -9x
Answer: -9x

Step-by-step explanation:
Answer:
circumference is 18.84
area is 28.26
Step-by-step explanation:
circumference of a circle is
2πr where r is radius
= 6×3.14= 18.8
area of a circle is πr²
= 3×3×3.14
= 28.26
use π = 3.14
