X + 2x + 3 + 3 = 3(x + 2)

Step-by-step explanation:

x + 2x + 3 + 3 = 3(x + 2)

Do the distributive property

x + 2x + 3 + 3 = 3 * x + 3 * 2

x + 2x + 3 + 3 = 3x + 6

Combine like terms

3x + 6 = 3x + 6

Subtract 6 on both sides

3x + 6 - 6 = 3x + 6 - 6

3x = 3x

As you can see, they are the same...which means

Any value of  x  makes the equation true.  All real numbers

1, 2, 3 , 4 etc

Any value u put into the equation to represent "x" will be true...

EX:

3x = 3x

( if x were 7 we substitute that)

3(7) = 3 (7)

21 = 21 CORRECT

They will be the same answer/ have the same value.

Hope this helped!

Have a day!

answer is 144

step-by-step explanation:

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
