Solve for x.
8x=4x-32
Subtract 4x from both sides.
4x=-32
Divide by 4 on both sides.
x=-8
answer: x=-8
<h3><u>Given</u>:</h3>
- A rectangle has a height of 4 and a width of x² + 3x + 2.
<h3><u>To find</u>:</h3>
- The area of the entire rectangle.
<h3><u>Solution</u>:</h3>
Hence, we know that area of rectangle is equals to the product of length and breadth.
Therefore, the area of rectangle is,

Therefore, the answer is 4x² + 12x + 8.
Answer:
D. 0.821
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The combinations formula is important to solve this question:
is the number of different combinations of x objects from a set of n elements, given by the following formula.

Desired outcomes
The order is not important. For example, Elisa, Laura and Roze is the same outcome as Roze, Elisa and Laura. This is why we use the combinations formula.
At least 3 girls.
3 girls
3 girls from a set of 5 and 2 boys from a set of 3. So

4 girls
4 girls from a set of 5 and 1 boy from a set of 3. So

5 girls
5 girls from a set of 5


Total outcomes
5 from a set of 8. So

Probability

So the correct answer is:
D. 0.821
