What is the value of the expression below when z=3 ? 9z^(2)-5z+10 Answer:

Substitute z value: Substitute the value of z into the expression. We are given z=3 and the expression 9z^(2)-5z+10. Let's substitute z with 3. 9(3)^(2) - 5(3) + 10Calculate square of z: Calculate the square of z, which is 3 in this case. (3)^(2) = 3 * 3 = 9 Now we can rewrite the expression with this value. 9(9) - 5(3) + 10Multiply coefficients and terms: Multiply the coefficients by their respective terms. 9(9) = 81 5(3) = 15 Now we can rewrite the expression with these values. 81 - 15 + 10Perform addition and subtraction: Perform the addition and subtraction in the expression. 81 - 15 = 66 Now add 10 to 66. 66 + 10 = 76

Q. What is the value of the expression below when

z=3

\newline

9 z^{2}-5 z+10

\newline

Answer:

Substitute z value: Substitute the value of $z$ into the expression. $\newline$ We are given $z=3$ and the expression $9z^{2}-5z+10$ . Let's substitute $z$ with $3$ . $\newline$ $9(3)^{2} - 5(3) + 10$
Calculate square of $z$ : Calculate the square of $z$ , which is $3$ in this case.$3^{ $2$ } = $3$ \times $3$ = $9$ $Now we can rewrite the expression with this value. $9(9) - 5(3) + 10$
Multiply coefficients and terms: Multiply the coefficients by their respective terms. $\newline$ $9(9) = 81$ $\newline$ $5(3) = 15$ $\newline$ Now we can rewrite the expression with these values. $\newline$ $81 - 15 + 10$
Perform addition and subtraction: Perform the addition and subtraction in the expression. $81 - 15 = 66$ Now add $10$ to $66$ . $66 + 10 = 76$
