80
* 40
3100, I would say yes because you have more than 1,000 cans in all the bags together.

Factor completely : (x^2+x-6)(2x^2+4x)

Elodia [21]

Answer:

(x+3)(x-2)(2x)(x+2)

Step-by-step explanation:

First, start by factoring (x²+x-6).

Find 2 numbers that multiply to -6 and add to get 1. This will be 3 and -2.

So, (x²+x-6) will factor into (x+3)(x-2)

Then, factor (2x²+4x).

You can factor out 2x because both terms can be divided by that.

You will be left with 2x(x+2), which cannot be factored anymore.

Combine all the factors to get (x+3)(x-2)(2x)(x+2).

Casey sells half of his video games. The next day he buys 3 more. He now has 27. How many video games did Casey have at the begi

Llana [10]

To solve this, it is helpful to set up an equation that reductions and additions of the games. The equation would be:

27 = 1/2v + 3

In this equation, v = the original number of video games. The 1/2 signifies Casey selling his games, and the + 3 shows Casey buying three more.

If we subtract 3 from both sides, we see that 1/2v = 24. Finally, we can multiply each side by 2 to isolate the variable, v, and we get v = 48.

Therefore our final answer is 48 video games.

Hope this is helpful!

Find the exact length of the curve.<br> x = 5 + 9t2, y = 4 + 6t3, 0 ≤ t ≤ 3

kodGreya [7K]

The exact length of the curve given the following system of inequalities is ≈ 1637.

<h3>What is a system of inequalities?</h3>

A system of inequalities refers to a set of two or more inequalities with one or more variables. This kind of system is used when a problem needs a range of solutions a there is over one constraint.

<h3>What is the length of the curve with the above system of inequalities?</h3>

Step One - Let's restate the equations

We have:

x = 5 + 9t²

y = 4 + 6t³

Where

0 ≤ t ≤ 3

Step 2 - Differentiate them

The first derivative of dx/dt

= d/dt [9t² + 5)

= 9 * (d/dt) (t²) + (d/dt) (5)

= 9.2t + 0

= 18t

Also differentiate (dy/dt)

= d/dt [6t² + 4]

= 6 * (d/dt) [t³] + (d/dt) [4]

= 6.3 t² + 0

= 18t²

To find the length of the arc:

L = $\[ \int_{0}^{4} \sqrt{(\frac{dx}{dt})^{2} + (\frac{dy}{dt})^{2} dt }$

We can thus deduce that:

= $\[ \int_{0}^{4} \sqrt{(\fra18t)^{2} + ({18t^{2} )^{2} dt }$

= $\int_{0}^{4}[18t \sqrt{1 + {18t^{2} ]$

Compute the definite integral and factor out the constraints and we have:

dt = 4912/3

≈ 1,637.3

Hence the exact length of the curve is

≈ 1637
