<span>A = l x w
Since
l = 3w
Substitute the l with 3w
The formula will be
A = 3w + w
A = 4w
An example:
The
given known values are: Length of 4 cm Width is unknown Perimeter is 34
cm Find the dimensions of the rectangle. Since the geometric formula
for perimeter is: </span>
P= 2 (l + w)
L = 2w – 4 cm
W =?
Derivation and solution:
34 = 2 (2w - 4) + 2w <span>
34 = 4w – 8 + 2w</span>
42 = 6w 42/6 = w
W = 7 cm
34 = 2l + 2(7)
34 = 2l + 14
2l = 34 – 14
2l = 20
L = 20/2
L = 10 cm<span> <span>

Answer:
no because 3/20 is eguivilent to 0.15 whitch is half of 0.3
Answer:
The distance is 32
Step-by-step explanation:
One way is to subtract -12 and 20, which equals 32.
Another way is to add 12 and 20 since distance on a number line is always positive, which equals 32.
Answer:
0
Step-by-step explanation:
4x+ 2( 3 – 3x) = 6
4x+6-6x=6
6-2x=6
6-6=2x
0/2=x
x=0
Get the decimal version of 26% by moving the decimal (at the end) over to spots, giving you .26. Multiply 50 by this, and you get .26*50=13. : )
