What is the value of the expression below when y=4 ? y^(2)+7y+9 Answer:

Substitute y value: Substitute the value of y into the expression. We are given y = 4, so we substitute 4 into the expression y^2 + 7y + 9. Calculation: (4)^2 + 7(4) + 9Calculate y^2: Calculate the value of y^2, which is 4^2. Calculation: 4^2 = 16Calculate 7y: Calculate the value of 7y, which is 7 times 4. Calculation: 7 * 4 = 28Add results: Add the results from Step 2 and Step 3, and then add 9. Calculation: 16 + 28 + 9Perform final addition: Perform the addition to find the final value. Calculation: 16 + 28 + 9 = 44 + 9 = 53

Q. What is the value of the expression below when

y=4

\newline

y^{2}+7 y+9

\newline

Answer:

Substitute y value: Substitute the value of $y$ into the expression. $\newline$ We are given $y = 4$ , so we substitute $4$ into the expression $y^2 + 7y + 9$ . $\newline$ Calculation: $(4)^2 + 7(4) + 9$
Calculate $y^2$ : Calculate the value of $y^2$ , which is $4^2$ . $\newline$ Calculation: $4^2 = 16$
Calculate $7y$ : Calculate the value of $7y$ , which is $7$ times $4$ . $\newline$ Calculation: $7 \times 4 = 28$
Add results: Add the results from Step $2$ and Step $3$ , and then add $9$ . $\newline$ Calculation: $16 + 28 + 9$
Perform final addition: Perform the addition to find the final value. $\newline$ Calculation: $16 + 28 + 9 = 44 + 9 = 53$
