Hey there!

YOUR CORRECT ANSWER TO THIS QUESTION WOULD ACTUALLY BE THE LAST OPTION. THIS WOULD BE CONSIDERED TO BE (NOT TRUE).

The reason why I would say this is because, there would be not way on how that $\left[\begin{array}{ccc}\boxed{\boxed{PQ=QR}}\end{array}\right]$ . They're are obviously to different sizes in this shape, this is why the last option would be your correct answer.

Hope this helps you!

That would be a true statement according to the lettered points. If you’ll notice, all the way around the figure, the letters are in that order. Therefore, yes it qualifies as a rectangle.

A²,b²,c² are consecutive perfect squares.How many natura numbers are lying between a² and c², if a>0

pogonyaev

Answer:

The quantity of natural numbers between $a^{2}$ and $c^{2}$ is $2\cdot (a + b) + 1$ .

Step-by-step explanation:

If $a^{2}$ , $b^{2}$ and $c^{2}$ are consecutive perfect squares, then both $a$ , $b$ and $c$ are natural numbers and we have the following quantities of natural numbers:

Between $b^{2}$ and $c^{2}$ :

$c^{2} = (b+1)^{2}$

$c^{2} = b^{2}+2\cdot b + 1$

$c^{2}-b^{2} = 2\cdot b + 1$

And the quantity of natural numbers between $b^{2}$ and $c^{2}$ is:

$c^{2}-b^{2}-1 = 2\cdot b$

Between $a^{2}$ and $b^{2}$ :

$b^{2} = (a + 1)^{2}$

$b^{2} = a^{2} +2\cdot a + 1$

$b^{2}-a^{2} = 2\cdot a + 1$

And the quantity of natural numbers between $a^{2}$ and $b^{2}$ is:

$b^{2}-a^{2}-1 = 2\cdot a$

And the quantity of natural numbers between $a^{2}$ and $c^{2}$ is:

$Diff = 2\cdot a + 2\cdot b + 1$

Please observe that the component +1 represents the natural number $b^{2}$

How do you simplify this sum?

snow_lady [41]

Answer:

Step-by-step explanation:

You can't simplify the sum, but you can factor it.

t^2 + 2t - 3

(t + 3)(t - 1 )

That's about all you can do.

6. Why is it helpful to have both lines on the same graph? (2 points)

Eva8 [605]

Answer:Line graphs can give a quick analysis of data. You're able to quickly tell the range, minimum/maximum, as well as if there are any gaps or clusters. This also means that it can easily observe changes over a certain period of time. When drawing them, you're able to use exact values from your data.

If g x 3x 5 then g 1 x

Ray Of Light [21]

G(x) = 3x + 5
y = 3x + 5
3x = y - 5
x = (y - 5)/3

Therefore, g^-1(x) = (x - 5)/3
