1.) Is this number rational or irrational?

Answer:

1) Irrational.

2) Irrational.

Step-by-step explanation:

We have been given two numbers. We are asked to determine whether the given numbers are rational or irrational.

We know that a number is a known as rational number, when we can represent it as a fraction or it has terminating decimals.

A number is a known as rational number, when it has non-repeating and non-terminating decimals.

1). $-\frac{\sqrt{3}}{5}+10.8$

$-0.3464101615137755+10.8=10.4535898384862245$

Since our given number has non-repeating or non-terminating decimal, therefore, given number is an irrational number.

2) $\sqrt{3}=1.7320508075688773$

Since our given number has non-repeating or non-terminating decimal, therefore, given number is an irrational number.

Can someone please do this i suck at math

Wittaler [7]

Answer:

Width = y + 7x

Step-by-step explanation:

Area of the rectangle = ${y}^{2} + 8xy + 7 {x}^{2}$

Length of the rectangle = $y + x$

Lets factorise ${y}^{2} + 8xy + 7 {x}^{2}$

$= > {y}^{2} + xy + 7xy + {x}^{2}$

$= > y(y + x) + 7x(y + x)$

$= > (y + 7x)(y + x)$

Now ,

Width = $\frac{Area}{Length} = \frac{(y + 7x)(y + x)}{(y + x)} = y + 7x$

Kiran wrote the expression x-10 for this number puzzle: "Pick a number, add -2, and multiply by 5."

ioda

Answer:

If you pick the number 2, you will get (2) - 10 = 8

But the way he said it, it would be: (2) - 2 * 5 = 0

The correct way would be to write the expression: (x - 3) * 5
