Answer:
108 - 30x - 116x² - 18x³
Step-by-step explanation:
We have to get the value of - (2x + 12) (9x² + 4x - 9)
Now, using the distributive property of multiplication we get
- (2x + 12) (9x² + 4x - 9)
= -[2x (9x² + 4x - 9) + 12 (9x² + 4x - 9)]
= -[(18x³ + 8x² - 18x) + (108x² + 48x - 108)]
= -[18x³ + 116x² + 30x - 108]
= 108 - 30x - 116x² - 18x³ (Answer)
Complete question:
<em>Write the verbal statement as an equation using x as a variable. Then solve. 2 more than 3 times a number is 17.
</em>
<em />
The required expression is 3x + 2 = 17 and the value of x is 5
Let the unknown number be x
- 3 times a number is expressed as 3x
- 2 more than3 times the number is 3x + 2
If the result is equivalent to 17, the required expression will be 3x + 2 = 17
Solve the resulting expression:
3x + 2 = 17
3x = 17 - 2
3x = 15
x = 15/3
x = 5
Hence the required expression is 3x + 2 = 17 and the value of x is 5

Answer:
Please look at the image
From the info 2 jars with 106 sprinkles each, we know 1 jar would have 53 sprinkles.
1 jar has 53 sprinkles.
6 jars have 318 sprinkles because:
6 × 53 = 318
13 jars have 689 sprinkles because:
13 × 53 = 689
Answer:
B) (x -1)(x - 8)
Step-by-step explanation:
x = 1 and x = 8
x - 1 = 0 --->x = 1
x - 8 = 0--> x = 8
answer B) (x -1)(x - 8)
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.
Let me know if you have any further questions.
