What is the value of  y2+5y
  when  y=4
 ?

Substitute 4 for y:  42+5(4)
 .

Type the numbers that complete each step.

42+5(4)
 

  +
  (
)

16+20
  = 


Let's solve the expression step by step:

When \( y = 4 \), the given expression is \( y^2 + 5y \).

Substitute \( y = 4 \) into the expression:

\[
4^2 + 5(4)
\]

Now calculate:

1. \( 4^2 = 16 \)
2. \( 5(4) = 20 \)

So, the expression becomes:

\[
16 + 20 = 36
\]

Thus, the value of \( y^2 + 5y \) when \( y = 4 \) is \( 36 \).
