Answer:

$x^{2}$ +5x-36

Step-by-step explanation:

To multiply binomials there are 2 ways. F.O.I.L., or the box method.

I will use the box method, and I hope it helps you!

After looking at the picture, this is not the answer quite yet.

$x^{2}$ $+9x$ $-4x\\$ $-36$

Subtract 4x from 9x.

9x-4x=5x

So, the answer will be $x^{2}$ +5x-36

Answer:

x^2 + 5x - 36

Step-by-step explanation:

Hello!

For this equation, we are going to multiply both binomials using FOIL.

FOIL stands for:

First

Outside/Outer

Inside/Inner

Last

This tells you the order in which you multiply two binomials in parentheses.

Let's get started!

First: x * x = x^2

Outside: x * -4 = -4x

Inside: 9 * x = 9x

Last: 9 * -4 = -36

x^2 - 4x + 9x - 36

These problems usually involve combining like terms, which is what we have to do here: -4x + 9x = 5x

And there you have it!

x^2 + 5x - 36

If you have any questions, just comment!

Hope I helped!

Hello!

So, this is quite the complex question, and here are the following steps:

What is the quotient of $\frac{6-3\sqrt[3]{6}}{\sqrt[3]{9}}$ ?

$\frac{(6 - 3\sqrt[3]{6})\sqrt[3]{9^{2}}}{9}$ (rationalize the denominator)

$\frac{3(2 -\sqrt[3]{6})\sqrt[3]{9^{2}}}{9}$ (factor 3 from the expression)

$\frac{(2-\sqrt[3]{6})\sqrt[3]{9^{2}}}{3}$ (reduce the fraction with 3)

$\frac{2\sqrt[3]{9^{2}}-\sqrt[3]{9^{2}}}{3}$ (distributive property)

$\frac{2\sqrt[3]{81}-\sqrt[3]{486}}{3}$ (simplify 3 · 9²)

$\frac{6\sqrt[3]{3}-3\sqrt[3]{18}}{3}$ (simplify the radical)

$\frac{3(2\sqrt[3]{3}-3\sqrt[3]{18})}{3}$ (factor 3 from the expression)

$2\sqrt[3]{3}-\sqrt[3]{18}$ (reduce the fraction)

The answer, is simply, choice A, $2\sqrt[3]{3} -\sqrt[3]{18}$ ≈ 0.263758.

Suppose that a bored student wants to go to a restaurant for lunch, but she only has an hour in which to go, eat, and get back i

Missing information

Take local speed ad 30 mph and express your answer in miles

Answer:

7.5 miles

Step-by-step explanation:

Time for lunch is 1 hour but once will wait for 30 minutes before served and eat.

Out of 1 hour, 30 mins is for service and eating to mean time to get from work to restaurant, to and fro is the other 30 mins

Since 30 mins is for to and fro, then one way direction takes 15 mins.

Speed, s=d/t and distance d=speed*time

Given local speed of 30 mph and time as 15 mins,

To convert minutes to hours, we divide it by 60 hence the distance is

30*15/60=7.5 miles

Therefore, the student can go to a restaurant that is 7.5 miles from the office.

IRINA_888 [86]

Answer:

10 units

Step-by-step explanation:

Allow me to revise your question for a better understanding.

<em>"In the xy-plane, the parabola with equation y = (x − 11) ² intersects the line with equation y = 25 at two points, A and B. What is the length of AB" </em>

Here is my answer

Because the parabola intersects the line with equation y = 25 Substituting y = 25 in the equation of the parabola y = (x - 11)², we get

25 = (x - 11)²

<=>x - 11 = ± 5

<=> $\left \{ {{x=6} \atop {x=16}} \right.$

Thus A(16, 25) and B(6, 25) are the points of intersection of the given parabola and the given line.

So the length of AB = √[(16 - 6)² + (25 - 25)²]

= √100 = 10 units
