Simplify each expression. 2d(3)

6d

Step-by-step explanation

First, you need to multiply 2d by 3, which you'll get 3d.

Next, multiply both numbers (2d and 3d) and you'll have 6d because 2 times 3 equals 6 but, since you have valuables you'd have to put d as the valuables of both numbers then multiply the numbers.

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
