Answer

3x-5

Q2) $(+5) - (-8) + (10)$ is called a math expression.

Q3) Calculate the following: A) $3x-5=$ This expression cannot be simplified further without a specific value for $x$ . $3x-5 = 3x-5$

B) $(-9) \times 10=$ Step 1: Multiply the absolute values. $9 \times 10 = 90$ Step 2: Apply the sign rule (negative $\times$ positive = negative). $(-9) \times 10 = -90$

C) $(-12) \times f =$ This expression cannot be simplified further without a specific value for $f$ . $(-12) \times f = -12f$
