Ymorist [56]

Answer:

Okay, so basically we have:
w as width; and 6+w as length

Perimeter=2w+2l

just substitute it with the values of width and length

P=2w+2(6+w)

P=4w+12

How to find the smallest integer k such that 60k is a perfect square
suter [353]

9514 1404 393

Answer:

  k = 15

Step-by-step explanation:

Look for the missing factors that make all of the factors of 60k be squares.

  60 = 2² × 3 × 5

The factors 3 and 5 each have an odd exponent (1), so those two factors must be part of k.

  60k = 2² × 3 × 5 × k

is a perfect square when ...

  3 × 5 = k = 15

For k = 15, 60k = 900 = 30²
