9514 1404 393

  k(w) = (w +3)²

Step-by-step explanation:

The name of the function is k, and its input is w, so the left side of the equal sign will be ...

  k(w)

This is said to be the square of the sum w+3, so the right side of the equal sign will be ...

  (w +3)²

The function equation in function notation is ...

  k(w) = (w +3)²

b mark me branliest thx

step-by-step explanation:

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
