What is the value of x... 5(x-5)=3(x-7)

timurjin [86]

Answer:

x=2

Step-by-step explanation:

5(x-5)=3(x-7)

Distribute

5x-25 = 3x-21

subtract 3x from each side

5x-25-3x = 3x-21-3x

2x-25 = -21

Add 25 to each side

2x-25+25 = -21 +25

2x=4

Divide by 2

2x/2 =4/2

x=2

The vertices of square RSTV have coordinates R(-1,5), S(-3,1), T(-7,3), and V(-5,7). What is the perimeter of RSTV?

kompoz [17]

The perimeter of square RSTV is: 17.88 units

Further explanation:

As the given figure is a square, all of its sides will be equal. So we have to find one side to find the perimeter.

Given

R(-1,5), S(-3,1), T(-7,3), and V(-5,7)

The distance formula will be used to find the side

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^@}$

Let x be one side of square

$RS=x=\sqrt{(-3-(-1))^2+(1-5)^2}\\=\sqrt{-3+1)^2+(-4)^2}\\=\sqrt(-2)^2+(-4)^2}\\=\sqrt{4+16}\\=\sqrt{20}\\=4.47$

Let P be the perimeter of square

P= 4x

P=4*4.47

=17.88 units

The perimeter of square RSTV is: 17.88 units
