How do i solve this.

nignag [31]

Let us set up some variables:

L: Length
W: Width

Now let us set up some equations based on the facts:

length of rectangle is 4 times its width --> L = 4W
perimeter of rectangle is 80 --> 2L + 2W = 80

Equations:

L = 4W -- equation 1

2L + 2W = 80 -- equation 2

Plug the value of L from equation 1 into equation 2

2(4W) + 2W = 80

8W + 2W = 80

10W = 80

W = 8 -- equation 3

Plug the value of W from equation 3 into equation 1:

L = 4W = 4 * 8 = 32

Therefore the length is 32 and the width is 8.

Hope that helps!

1. Given line segment RB and on it is point C, if RB = 45 and CB = 3x - 12 and RC = 2x + 9, what is the value of x?

marshall27 [118]

Answer:

Step-by-step explanation:

1). If a point C is lying on a line segment RB,

Then RB = RC + CB

Since, RB = 45, CB = 3x - 12 and RC = 2x + 9

45 = (2x + 9) + (3x - 12)

45 = (2x + 3x) - 3

48 = 5x

x = $\frac{48}{5}$

x = 9.6

2). Since, RC = 2x + 9

RC = 2(9.6) + 9

= 19.2 + 9

= 28.2 units

3). Distance between the two points $(x_1,y_1)$ and $(x_2,y_2)$ is given by the formula,

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

Distance between the points A(2, -2) and D(-2, 2) will be,

$AD=\sqrt{(2+2)^2+(-2-2)^2}$

= $\sqrt{16+16}$

= $4\sqrt{2}$

= 5.657

≈ 5.66 units
