Answer:

4y^{2}+3y  

Step-by-step explanation:

First you need to distribute the values.  

(4y+3)(2y) Using the "Rainbow Method" to multiply the polynomials  

You Should get  

8y^{2}+6y  

Since this is the area of the rectangle and we need to find the area of the shaded region you need to dived 8y^{2}+6y in half because the shaded region is half of the rectangle.  

8y^{2}+6y/2  

Doing this you will get  

4y^{2}+3y

Answer:

Distance cover by Alyson = 16 miles

Step-by-step explanation:

Given:

Distance cover together = 39 miles

Assume;

Distance cover by Jeff = a

Distance cover by Alyson = a - 7

Find:

Distance cover by Alyson

Computation:

a + (a - 7) = 39

2a - 7 = 39

2a = 46

a = 23

Distance cover by Alyson = a - 7

Distance cover by Alyson = 23 - 7

Distance cover by Alyson = 16 miles

Answer:

  yes

Step-by-step explanation:

The side lengths of the triangle are 5, 12, and 5+8 = 13. We can check to see if they satisfy the Pythagorean theorem, which would indicate a right triangle.

  5² + 12² = 25 +144 = 169 = 13²

These sides do satisfy the relationship between sides for a right triangle, so angle A is a right angle. That is the case when segment AB is a tangent to the circle.

  Yes, AB is a tangent.

Answer:

$10.50

Step-by-step explanation:

Interest = future value - amount saved

The formula for calculating future value:

FV = P (1 + r)^n

FV = Future value  

P = Present value  

R = interest rate  

N = number of years

$50 x (1.1)^2 = $60.50

Interest = $60.50 - $50 = $10.50

I got you bro!

Answer:

{x,y} = {4-1}

You might be wondering how I got this, well here are the steps:

System of Linear Equations entered :

  [1]    2x + y = 7

  [2]    x - 2y = 6

Graphic Representation of the Equations :

   y + 2x = 7        -2y + x = 6  

Solve by Substitution :

// Solve equation [2] for the variable  x  

 [2]    x = 2y + 6

// Plug this in for variable  x  in equation [1]

  [1]    2•(2y+6) + y = 7

  [1]    5y = -5

// Solve equation [1] for the variable  y  

  [1]    5y = - 5

  [1]    y = - 1

// By now we know this much :

   x = 2y+6

   y = -1

// Use the  y  value to solve for  x  

   x = 2(-1)+6 = 4

Solution :

{x,y} = {4,-1}

I hope this has helped you and have a wonderful day!

Answer:

3.08 hours

Step-by-step explanation:

Preparation for the homecoming football game, members of the student body are painting the spirit rock in front of the school.

If Angela works alone, it will take her five and a half hours.

If Brandon works alone, it will take him 7 hours. If they work together, it will take them approximately hours ?

This is calculated as:

The Number of hours they worked together = T

1/5.5 + 1/7 = 1/T

= 7 + 5.5/(5.5)(7)

= 12.5/38.5

1/T = 12.5/38.5

Cross Multiply

12.5T = 38.5

T = 38.5/12.5

T = 3.08 hours

The time required when Angela and Brandon work together, for the preparation for the homecoming football game, is 3.08 hours.

The total time taken is inversely proportional to the rate of work. If a unit of work is done in total n number of days, then the total work done in a day can is,

[tex]W_1=\dfrac{1}{n}[/tex]

In preparation for the homecoming football game, members of the student body are painting the spirit rock in front of the school.

If Angela works alone, it will take her five and a half hours. The work done by Angela in one hour is,

[tex]A=\dfrac{1}{5.5}\\A=\dfrac{2}{11}[/tex]

If Brandon works alone, it will take him 7 hours. The  work done by Brandon in one hour is,

[tex]B=\dfrac{1}{7}[/tex]

The work done in one hour, when the work together,

[tex]A+B=\dfrac{2}{11}+\dfrac{1}{7}\\A+B=\dfrac{14+11}{77}\\A+B=\dfrac{25}{77}\\A+B=\dfrac{1}{3.08}[/tex]

Thus, the time required when Angela and Brandon work together, for the preparation for the homecoming football game, is 3.08 hours.
