Question

What is the value of 3(a-9) when a =6

Answer 1

Answer:

-9

Step-by-step explanation:

We are given the value of "a", which is 6. Let us substitute the value of "a" into the expression to determine a numerical value of 3(a - 9).

• ⇒ 3(a - 9)
• ⇒ 3[(6) - 9] . . . . . . . . {a = 6}

Open the parentheses to simplify the expression inside the long brackets [ ].

• ⇒ 3[(6) - 9] . . . . . . . . {a = 6}
• ⇒ 3[6 - 9]

Subtract the expression inside the long brackets [ ]

• ⇒ 3[6 - 9]
• ⇒ 3[-3]

Finally, simplify the product of 3 and -3.

• ⇒ 3[-3]
• ⇒ 3 × -3 = -9

Therefore, -9 is the value of 3(a - 9) when a = 6.
