Evaluate 8r-rs when r=6 and s=5.

Substitute values into expression: Substitute the given values for r and s into the expression. Expression: 8r - rs Substitute r = 6 and s = 5. Expression after substitution: 8(6) - (6)(5)Multiply 8 by 6: First, multiply 8 by 6. Calculate 8 * 6. 8 * 6 = 48Multiply 6 by 5: Next, multiply 6 by 5. Calculate 6 * 5. 6 * 5 = 30Subtract product of 6 and 5 from product of 8 and 6: Now, subtract the product of 6 and 5 from the product of 8 and 6. Subtract 30 from 48. 48 - 30 = 18

Q. Evaluate

\newline

8r - rs

when

\newline

r = 6

and

\newline

s = 5.

Substitute values into expression: Substitute the given values for $r$ and $s$ into the expression. $\newline$ Expression: $8r - rs$ $\newline$ Substitute $r = 6$ and $s = 5$ . $\newline$ Expression after substitution: $8(6) - (6)(5)$
Multiply $8$ by $6$ : First, multiply $8$ by $6$ . $\newline$ Calculate $8 \times 6$ . $\newline$ $8 \times 6 = 48$
Multiply $6$ by $5$ : Next, multiply $6$ by $5$ . $\newline$ Calculate $6 \times 5$ . $\newline$ $6 \times 5 = 30$
Subtract product of $6$ and $5$ from product of $8$ and $6$ : Now, subtract the product of $6$ and $5$ from the product of $8$ and $6$ . Subtract $30$ from $48$ . $5$ $0$
