3x^2 + 9x + 4x + 12
3x^2 + 13x + 12
Answer:
45
Step-by-step explanation:
Evaluate 5 x^2 - 3 (x - 2) + x where x = 3:
5 x^2 - 3 (x - 2) + x = 5×3^2 - 3 (3 - 2) + 3
3^2 = 9:
5×9 - 3 (3 - 2) + 3
3 - 2 = 1:
5×9 - 3 + 3
5×9 = 45:
45 - 3 + 3
45 + 3 = 48:
48 - 3
| 4 | 8
- | | 3
| 4 | 5:

Step - by - step explanation :
6 3/6 -- simplest form --> 6 1/2
6 6/12 -- simplest form --> 6 1/2
To figure out which is not equivalent to the others,, we must solve each option provided. x < -2 is already solved,, so there is no need to do any work that option.
The first step for solving x - 2 < 4 is to move the constant to the right side and then change its sign.
x < 4 + 2
Now add the numbers together to get your final answer.
x < 6
This means that we have one option that equals x < -2 and one option that equals x < 6.
Let's now solve 2x < -4 to see what that one equals. In order to solve this,, we need to divide both sides of the inequality by 2.
x < -2
Now we can see that it looks like all of the expressions are equivalent except for x - 2 < 4. Before we can confirm this though,, let's solve for x - 2 < -4. The first step for solving this is to move the constant to the right side and change its sign.
x < -4 + 2
Now calculate the sum of these two numbers to get your final answer.
x < -2
This tells us that all of the options are equivalent except for x - 2 < 4,, or option B.
