LN² = 7² + 8²

LN² = 49 + 64

LN = √113

In short, Your Answer would be: Option D

For the line segment whose endpoints are X(1, 2) and Y(6, 7), find the x value for the

finlep [7]

Answer:

3) 2.7

Step-by-step explanation:

The distance between two points $(x_1,y_1)$ and $(x_2,y_2)$ can be determined by:

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

Since the points are X(1, 2) and Y(6, 7). The distance between the two points is

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}=\sqrt{(6-1)^2+(7-2)^2}=\sqrt{50}$

the x value for the point located 1/3 the distance from X to Y,

$x=\frac{x_2-x_1}{3}=\frac{6-1}{3}=1.7$

The x value = $x_1+1.7 = 1+1.7 = 2.7$

the perimeter of one rectangle is 120cm. another rectangle with twice the length amd and one third the width has a perimeter of

fgiga [73]

Answer:

Dimensions of 1st rectangle,

length = 39 cm, width = 21 cm.

Dimensions of the 2nd rectangle,

length = 78 cm, width = 7 cm.

Step-by-step explanation:

Let the dimensions of the 1st rectangle be,

Length = x, width = y

so the dimensions of the 2nd rectangle becomes,

Length = 2x, width = y/3

perimeter of the first rectangle,

2(x+y)=120 --------- (i)

perimeter of the 2nd rectangle,

2(2x+y/3)=170 ---------(ii)

if we solve equation (i) and (ii), we'll get,

x = 39

y = 21

for the other rectangle, 2x = 78, y/3 = 7.
