The upper image is the equation and the lower image is the solution, and as you can see, the calculator is unable to give the answer and instead just gives error. This was not always so; I remember being able to solve polynomials for example, so something seems to have been changed, and I can’t figure out what.

It’s a shame because I like this calculator the most for it’s clean and simple web page.

I'm not sure how this applies to off-topic but...

Substituting 2 and -4 for m and n respectively,

-3(2)(-4)+4(2)-3= 29.

From the diagram, we know that AC is 2, and AD is sqrt3. We can also find DC which is (2^2) - (sqrt3^2)= 1. Since DC is 1, BD is also 1. We also know that BXD and ACD are similar. The corresponding sides BD and AD have the ratio's 1:sqrt 3 respectively. So if CD is 1, then it's corresponding side XD will be 1/sqrt 3 which simplifies to \(\frac{\sqrt{3}}{3}\) which is your answer.

20 - (9 * x) = -7

27 = (9 * x)

x= 3.

If two figures are similar the ratio of their areas is the same as the ratios of the squares of the corresponding sides.

PS and AD are corresponding sides; the squares of their ratio is:  27.5² / 11² 

The ratio of the area of PQRS to the area of ABCD is x / 54

Setting these two equal:  x / 54  =  27.5² / 11²    --->     x  =  54 · 27.5² / 11² 

"... lets say, 1 + x = 3, but right now the calculator only gives “Error” ..." 

You know that  1 + x = 3  gives an error message. 

Have you tried  x + 1 = 3  to see what happens then? 

Set the equations to be equal to each other, then solve for (x, y) for the intersection point

OR

Graph the equations. When y = 0, x = ?

When x = 0, y = ?

Do that for both of them.

OP here,

Sorry, I forgot to mention that I have tried deleting browser history, cache, cookies − all of it, so the calculator should be operating on default settings. But, still, it didn’t help whatsoever; the same problem persists: the calculator seems to be unable to solve for x.

If the prism (the box) has dimension 4" x 4" x 3", its volume is 48 cu. in.

If you place 38 1" cubes into this box, there is still room for 48 - 38  =  10 more 1" cubes.

OH THANK U SO MUCH !!!!

The probability that the top card is a 3 is 4/52 (because there are 4 threes and 52 cards).

The probability that the second card is an 8 is 4/51 (because there are 4 eights and 51 remaining cards).

To find the probability that both occur, multiply these numbers together:  (4/52) x (4/51)  =   ....     

Since triangle(ABC) is a right triangle, AC²  =  AB² + BC²   --->   AC²  =  5² + 3²   --->   AC²  =  34  

   --->   AC  =  sqrt(34)

To find BD, I'm going to find the area of triangle(ABC) in two ways.

First way  --  with base AB and height BC:  Area  =  ½·5·3  =  7.5

Second way  --  with base AC and height D:  7.5  =  ½·sqrt(34)·BD   --->   BD  =  15/sqrt(34)

Now, add these parts together ...

Polygon ABCD has the following vertices:
A(-4, 2), B(3, 2), C(3, -5), and D(-4,-2)
Calculate the area of the polygon.

EP is correct -- here's why.

There are two lines on the graph, one going from lower left to upper right, the other going from upper left to lower right.

The equation y = x + 3 has a positive slope, so it is the equation of the line that goes from lower left to upper right.

Including the "less than symbol", y <= x + 3 is shaded below this line; so either #2 or #3 could be correct.

The equation y = -2x -2 has a negative slope, so it is the equation of the line that goes from upper left to lower right.

Including the "greater than" symbol, y >= -2x - 2 is shaded above this line; so either #3 or #4 could be correct.

Combining our answers, we have #3.

what do you mean by "all s?"

Graph #3

Lemme make it more detailed. Because they have the same remainder, then it must be the lcm so the multiple is the same. lcm of 9,12=36, and because there is a remainder of 2 36+2=38

I think the answer is C.

Let's use an example. 

z=100

x would equal 105

but, 5 percent less than 105 is 99.75

So, z is bigger than y, smaller than x
