The maximum value of the box is 361.186in³

Given,

In the question:

The dimension of the cardboard is given as:

Length of the cardboard is = 23

Width of the cardboard is = 13

and, squares with sides of length x

To find the volume of the largest box that can be formed in this way.

Now, According to the question:

Assume the cut-out is x.

So, the dimension of the box is:

Length = 23

Width = 13

Height = x

The volume of the box will be:

V = (23 - 2x ) (13 - 2x)x

V = 299 - 72x² + 4x³

Differentiate w.r.t to x

V = 299 - 144x + 12x²

Set to 0

V = 299 - 144x + 299 = 0

we have:

x = (2.67, 9.33)

9.33 is greater than the dimensions of the box.

So, the possible value of x is:

x = 2.67

Recall that:

V = 299 - 72x² + 4x³

So, we have:

V = 299 (2.67) - 72 (2.67)² + 4(2.67)³

Hence, the maximum value of the box is 361.186in³

What four consecutive intergers have a sum of -34
Ivenika [448]

Answer:

-7, -8 , -9 and -10 are such four integers.

Step-by-step explanation:

Let the first integer = k

So, the next three consecutive integers are ( k+1), ((k + 1) + 1)  and (((k + 1) + 1) +1)

or, k , (k +1), (k +2) and (k +3) are four consecutive integers.

Now, their sum is -34.

⇒k   + (k +1) +  (k +2) +  (k +3)  = -34

or, 4k  + 6 = -34

or, 4k = - 34 - 6 = -40

⇒  k = -40/ 4 = -10

Hence, the first integer k = -10

The next integer = k + 1 = -10 + 1 = -9

Similarly next two integers are -8 and - 7.

So -7, -8 , -9 and -10 are such four integers.

2 and 4 seemed really confusing , please help :(
artcher [175]
2. This question is basically asking you to factor 6x² - x - 12, so that one bracket is (2x - 3) and the other bracket is your answer. If you do factor 6x² - x - 12, you get (2x - 3)(3x + 4), so your answer would be J. 3x + 4.

4. Again you are factoring, so you would get your answer as (x + 3)(x - 2), which is answer F.

I hope this helps! Let me know if you would like me to show you how I factored :)
