The length of a rectangle is 4 more than 3 times the width if the perimeter of the rectangle is 18.4 cm what is the area of the

garik1379 [7]

Let's call the width: w

the lenght is then 3w+4 ("4 more than 3 times the width")

and the parameter would be 2(w+3w+4), that is 2*(4w+4), that is 8w+8.

this is also equal to 18.4:

8w+8=18.4
8w=10.4
w=1.3

this is the width, and the lenght is:
4+3*1,3=4+3.9=7.9

and the area is their product:
1.3*7.9=10.27

Complete the slope-intercept form of the linear equation that represents the relationship in the table.

Mrac [35]

The equation of the line that passes through points (-1, -10), and (3, 14) is y = 6x - 4.

<h3>What is a straight line?</h3>

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

$\rm m =\dfrac{y_2-y_1}{x_2-x_1}$

We have two points shown in the table:

(-1, -10), and (3, 14)

$\rm (y - 14 )= \dfrac{14+10}{3+1}(x-3)$

y - 14 = 6(x - 3)

y = 6x - 4

Thus, the equation of the line that passes through points (-1, -10), and (3, 14) is y = 6x - 4.

Another correction (Tried these on my own hand but got confused)

kirill115 [55]

Answer: Triangle: x = 40 Line: x = 10

Explanation:
All angles of a triangle adds up to 180. So x + 50 + 90 (the square box represents a 90° angle) = 180
Simplify: x + 140 = 180
So x = 40°

A straight line is 180°
so 7x+110=180
7x= 70
x=10
