Which expression correctly represents the perimeter of a rectangle that is 12 centimeters long and 7 centimeters wide?
1 answer:
Answer:
The expression for the perimeter of the rectangle is:
P = 2*(12 cm) + 2*(7 cm)
And the perimeter is:
P = 38cm
Step-by-step explanation:
We know that for a rectangle of length L and width W, the perimeter is given by:
P = 2*L + 2*W
So, if we have a rectangle that is 12 cm long, we have L = 12cm
and if the rectangle is 7cm wide, we have W = 7cm
Now we can replace these in the perimeter equation to get:
P = 2*(12 cm) + 2*(7 cm)
P = 24cm + 14cm
P = 38cm

Step-by-step explanation:
1 km = 1000 m
1 hour = 3600 s
so,
37.6 km = 37,600 m (still per hour or per 3600 s).
in 1 second now that is

Answer:
ln [(x + 2)^3 ]/(x-1)
Step-by-step explanation:
3ln(x+2) - ln(x - 1) = ln (x + 2)^3 - ln (x-1)
ln (x + 2)^3 - ln (x-1) = ln [(x + 2)^3 ]/(x-1)
