Answer:

5.(x+7)(4x2+7)

6.(b−3x)(3x2−1)

Answer:

Area:80mi^2

Perimeter:40mi

Step-by-step explanation:

Answer:

6 x 14 = 84

84 x 2(since there are two small rectangles) = 168

22 x 6 = 132

132 x 2 = 264

264 x 2(since there are two of the same shape) = 528

22 x 14 = 308

308  x 2(since there are two of the same shape) = 616

Now we add up all the areas:

168 + 528 + 616 = 1312 square cm is your answer.

The median of the list of numbers is 4

The numbers are given as:

3, 5, 2, 10, 6, 3, 7, 3

Sort the numbers in ascending order

2, 3, 3, 3, 5, 6, 7, 10

The median is the middle number.

The middle numbers in the above data are 3 and 5

So, the median is:

Median =(3 + 5)/2

Answer:

x+6=y and 3x=12

Step-by-step explanation:

Let x be the distance traveled by Bryan and let y be the distance traveled by Sam then the first equation would be:

x+6=y (x plus 6 is equal to y, Bryan's distance plus 6 is equal to Sam's distance) and the second one is:

3x=12 (3 times x is 12, 3 times the distance travelled by Bryan is 12)

So our statements/equations are:

x+6=y and

3x=12 (we dont write this as x=4 as it asks us to give the statements we got from the information given, we only start simplifying once it tells us to solve)

since it is addition, you can just remove the parentheses without doing anything else. Then just add the ones with the same coefficients.

The solution to this system of linear equations is x = 3, y = 2.

2x - 3y = 3

2x = 3 + 3y

2x = 3y + 3

x = (3y + 3) / 2

x = 3/2 + 3/2y

x = 3, y = 2

This system of linear equations features two unknown variables, x and y. The equation 2x - 3y = 3 can be rearranged into 2x = 3y + 3. This equation can then be solved for x by dividing both sides by 2, resulting in x = 3y + 3/2. Since 3y + 3/2 must equal 3, this means that y must equal 2. Substituting 2 for y in the original equation yields 2x = 3 + 3(2), or 2x = 9. Dividing both sides by 2 yields x = 9/2, or x = 3. Therefore, the solution to this system of linear equations is x = 3 and y = 2.

The solution to the system of linear equations 2x + 3y = 3 is x = 1 and y = -1/3.

1. Rewrite the equation in standard form is

2x + 3y = 3

2. Subtract 2x from both sides of the equation:

3y = 3 - 2x

3. Divide both sides by 3:

y = (3 - 2x)/3

4. Solve for x by substituting y in the original equation:

2x + 3(3 - 2x)/3 = 3

5. Simplify and solve for x:

2x + 3 - 2x = 3

x = 1

6. Substitute x into the equation y = (3 - 2x)/3

y = (3 - 2(1))/3

y = -1/3

Answer:

Step-by-step explanation:

Probability that the calendar turned to month of May or June is 1/6.

Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.

The value of probability will be always in the range from 0 to 1.

Total number of months = 12

Suppose that a calendar is turned.

Probability that the calendar turned to month of May = 1/12

Probability that the calendar turned to month of June = 1/12

Probability that the calendar turned to month of May or June = 1/12 + 1/12

                                                                                                      = 2/12

                                                                                                      = 1/6

Hence the probability that the calendar turned to month of May or June is 1/6.

The height of Dange who can jump 27.5% of her height is 10.4 inches.

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, Dange measures and finds that she can do a vertical jump that is 27.5 % of her height f and the distance of the jump is 13.2 inches.

Therefore. (100 + 27.5)% = 127.5% of f is 13.2 inches, This can be numerically expressed as,

(127.5/100)×f = 13.2.

1.275f = 13.2.

f = 13.2/1.27.

f = 10.4 feet.

So, The height of Dange is 10.4 inches.

Speed of the given object in centimeters per hour

= 0.23 cm / hour

Unit conversion is a process with multiple steps that involves multiplication or division by a numerical factor or, particularly a conversion factor. The process may also require selection of the correct number of significant digits, and rounding. Different units of conversion are used to measure different parameters.

Like 1 yard = 91.44 cm

1 month = 730 hrs.

Given,

Distance covered by the object = 11 yards

Distance covered in cm = 11 × 91.44 = 1005.84 cm

Time taken to cover 11 yards = 6 months

Time taken in hours = 6 × 730 = 4380 hrs.

Speed of the object = distance covered by the object / Time taken

Speed of the object = 1005.84/4380 = 0.2296 ≈ 0.23 cm per hour

Hence,  in centimeters per hour,

the speed of the object is 0.23 cm / hour.

Determine how many square centimeters make up a square meter in order to determine how long Marc will have brownies before they run out.

We must first determine the number of square centimeters in a square meter in order to determine how many days Marc has left of brownies before they run out. A square meter has 3.6 square meters in it.

Because of this, Marc has access to brownies for 3.6 days until they are finished.

Knowing the dimensions of a square or rectangle will allow you to compute its square meters. Also known as the shape's area, this term is used. Length times width equals m2, which is the formula used to calculate square meters. As an illustration, if your square is 3 meters long and 2 meters wide, 3 x 2 equals 6 meters2.
