2(x+1)=2x+2 if you factor the right side ..

2(x+1)=2(x+1)

This is always true for any value of x so there are infinitely many solutions...

In the center of town there is a square park with an area of 900 square feet. If Stephen walks from one corner of the park to th

Vedmedyk [2.9K]

The distance walked by Stephen is 42.42 feet

<h3>Solution:</h3>

Given that In the center of town there is a square park with an area of 900 square feet

Stephen walks from one corner of the park to the opposite corner

To find: Distance walked by Stephen

We need to find the distance that the person walk from one corner of the park to the opposite corner.

So, we need to find the Diagonal of the square park

The diagonal of square is given as:

$\text{ Diagonal } = \sqrt{2} \times \text{ side}$

Let us find the length of side of square

Given area of square = 900 square feet

The area of square is given as:

$area = (side)^2\\\\900 = (side)^2$

Taking square root on both sides,

$side = \sqrt{900} \\\\side = 30$

Thus length of each side of square is 30 feet

Therefore, length of diagonal is given as:

$diagonal = \sqrt{2} \times 30\\\\diagonal = 1.414 \times 30 = 42.42$

Hence, the distance that the person walks 42.42 feet

Find an inverse of 16 modulo 17. That is solve 16x=1(mod 17)

mote1985 [20]

Answer:

-1 is the inverse of 16 modulo 17.

Step-by-step explanation:

To find : An inverse of 16 modulo 17 i.e. $16x=1(mod 17)$ ?

Solution :

First we find the GCD of (17,16) using Euclid's algorithm,

$17=16\times 1+1$

Remainder is 1.

Which means, GCD(17,16)=1

Using back substitution we get,

$1=17-16(1)$

$\Rightarrow 16(-1)=1+17(-1)$

$\Rightarrow 16(-1)=1(\mod 17)$

i.e. -1 is the inverse of 16 modulo 17.

On comparing with $16x=1(mod 17)$

The value of x=-1.
