Answer:

Though many different types of expressions can be classified as binomials, not all of them can be factored. In order to be factorable, a binomial has to have a difference of two squares, a difference of cubes, a sum of cubes, or a greatest common factor.

Answer:

  9 ordered pairs

Step-by-step explanation:

The requirement that the harmonic mean of two positive integers be 20 places a restriction on what those integers may be.

  20 = 2/(1/x +1/y)

  y = 10x/(x -10)

Integer values of x that produce integer values of y are ...

  x ∈ {11, 12, 14, 15, 20, 30, 35, 60, 110}

The corresponding 9 ordered pairs are ...

  (11, 110), (12, 60), (14, 35), (15, 30), (20, 20), (30, 15), (35, 14), (60, 12), (110, 11)

Answer:

P = 6x + 16

Step-by-step explanation:

the perimeter (P) of a rectangle is calculated as

P = 2l + 2w ( l is the length and w the width ) , then

P = 2(2x + 3) + 2(x + 5) ← distribute both parenthesis

  = 4x + 6 + 2x + 10 ← collect like terms

  = 6x + 16

Answer:

the question is mistyped.. they are trying to ask for the area.. not are.. :P soooo ... to answer the question that is trying to be asked.. and not the one that is being asked.. b/c there isn't really an answer to what is the are.... :/

Step-by-step explanation:

area of a triangle is 1/2 area of the box that the triangle makes 1/2  hmm , hence the fomula.. 1/2*base*height....  b/c base*height is the area for a box... soooo ...

for this triangle it's 1/2* 3 * 4= 6  :)

note: even thou this is not a right triangle.. we still know the height of it.. the graph is showing us that.   so our formula still works... for this one  if we didn't know height.. we might have to use sin() or cos() to figure out height.. but here it's given. luckily  :)

Answer:

Step-by-step explanation:

The measure of each angle are 33 and 26 if the measure of angle m is 7 degrees less than the measure of angle n.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

The measure of angle m is 7 degrees less than the measure of angle n.

m = n - 7 ...(I)

The sum of the measures of the two angles is 59°

m + n = 59 ...(II)

Solving the above two linear equations in two variables by substitution method:

n - 7 + n = 59

2n = 66

n = 33

m = 33 - 7 = 26

Thus, the measure of each angle are 33 and 26 if the measure of angle m is 7 degrees less than the measure of angle n.

Step-by-step explanation:

for all of it you should do sum of angles in a triangle

Answer:

You make a table rounding up the times a card was drawn, then find the median. To find the median, find the middle number or the one that appears the most.

Answer:

42° and 48°

Step-by-step explanation:

Complementary angles add up to 90°.

So we have one angle x and the other angle x+6 which when added together will equal 90°.

x + x + 6 = 90

2x + 6 = 90

      -6    - 6

2x = 84

Divide both sides by 2

2x/2 = 84/2

x = 42

So one angle = 42°, and the other angle = 42° + 6° = 48°.

Answer:

Step-by-step explanation:

We know the diagonals of a parallelogram bisect each other.

If O is the point of intersection of diagonals, AC is split into AO and OC.

Since AO = OC, the length of AC is:

1. 24

2. 10.4

3. 12.8

so your basacually adding the number to itself

ex.

12.4+12.4= 24.8 that would be the answer

Step-by-step explanation:

since the lines only intersect each other once there is one solution at the point (1,4)

Answer:

C - One solution: x = 1, y = 4

Step-by-step explanation:

   The solution is where the lines intersect. We can see they only intersect at point, (1, 4), so the answer is C - One solution: x = 1, y = 4.

The minimum possible area of the square cardboard will be given as

[tex]a= 72.2\ in ^2[/tex]

The area of the square is the product of its two lengths.

We have an equation of the circular drink coaster

[tex]x^2+y^2=18.0625[/tex]

Comparing the above equation from the general form of the circle

[tex]x^2+y^2=r^2[/tex]

We can see that from the equation

[tex]r^2=18.0625[/tex]

[tex]r=4.25\ inch[/tex]

Diameter [tex]d=4.25\times 2=8.50[/tex]

The diameter will be the length of the square since the circle is cut from the square.

So the area of the square will be

[tex]a=d\times d=8.50\times 8.50=72.25\ inch^2[/tex]

Thus  the minimum possible area of the square cardboard will be given as  [tex]a= 72.2\ in ^2[/tex]

Step-by-step explanation:

The decline in the number of farms means there is a reduction in the number of farms

The number of US farms after 5 years is 3584818

The equation that represents the number of farms is given as:

[tex]y=3962000e^{-0.02t[/tex]

After 5 years, the value of t is 5.

So, we have:

[tex]y=3962000e^{-0.02*5[/tex]

Evaluate the product

[tex]y=3962000e^{-0.1[/tex]

Evaluate the exponent

[tex]y=3962000*0.9048[/tex]

Evaluate the product

[tex]y=3584817.6[/tex]

Approximate

[tex]y=3584818[/tex]

Hence, the number of US farms after 5 years is 3584818
