Grade: 6-a Lesson: S2-L4 |
Explanation: Hello Students, time to practice and review the steps for the problem. |
Lesson Steps
| Step | Type | Explanation | Answer |
|---|---|---|---|
1 |
Problem |
Simplify the expression ( 2x + 3 ) ( 1 ) using the multiplicative identity property. |
|
2 |
Step |
Given expression |
( 2x + 3 ) ( 1 ) |
3 |
Hint |
Symbolically, Multiplicative identity Property can be expressed as |
a × 1 = a, Where a is any number. |
4 |
Step |
Recognize that multiplying any expression by 1 does not change the expression. |
|
5 |
Step |
According to the multiplicative identity property |
( 2x + 3 ) ( 1 ) simplifies to 2x + 3 |
6 |
Step |
So, the final simplified expression is 2x + 3. |
|
7 |
Choice.A |
This option represents the expression 2x - 3. It’s not the result of applying the multiplicative identity property to the given expression (2x + 3) × 1 |
2x - 3 |
8 |
Choice.B |
This option doesn’t correspond to the given expression. It’s 3x + 2, which is unrelated to the multiplication by 1 |
3x + 2 |
9 |
Choice.C |
This option represents 3x - 2, which is not the result of applying the multiplicative identity property to the given expression |
3x - 2 |
10 |
Choice.D |
This option correctly represents the simplified expression. Applying the multiplicative identity property, we have (2x + 3) × 1 = 2x + 3 |
2x + 3 |
11 |
Answer |
Option |
D |
