The answer is 56 ft
The perimeter of the rectangle with width w and length l is:
P = 2w + 2l
We know:
w = 7 ft
l = 3w = 3 * 7 = 21 ft
P = 2w + 2l
P = 2 * 7 + 2 * 21
P = 14 + 42
P = 56 ft
Answer:
we know that
Hillary
swims every 6 days---> Multiples of 6---> 6-12-18-24-30-36-42-48-54
runs every 4 days-----> Multiples of 4----> 4-8-12-16-20-24-28-32-36-40-44-48
cycles every 16 days---> Multiples of 16---> 16-32-48-64
therefore
In 48 days she will do all three on the same day.
the answer is
48 days
Step-by-step explanation:
Step-by-step explanation:
3t + 4 = 19
3t = 15
Hence t = 5.
Leading coefficient = -3
Constant = 2
When you order them in standard form, you need to put them in ascending order of the exponents. Therefore the -3x^2 would come first, which makes the number attached (-3) the lead coefficient.
Also, since the number (2) without an x attached would be last (due to the power of x technically being 0), than that is the constant.
