The width of the rectangle
Nikolay [14]

Answer:

84cm^2

Step-by-step explanation:

P=2l+2w

We are given,

P=40cm

l=2w+2

Plug these into the first formula and solve for the dimensions,

length and width, of the rectangle:

40=2(2w+2)+2w              Simplify

40=4w+4+2w

40=6w+4

36=6w

6=w OR the width is 6cm, therefore,

the length is

l=2(6)+2

l=14cm

To calculate the area of a rectangle, A=lw,

plug the length,14cm, and the width, 6cm, into this formula

A=(14)(6)

A=84cm2 OR the area of the rectangle is 84cm^2

Graph y= –3x+4 <br> please help me
Inessa [10]
<span>This tells us two things. Our slope is 3 and our y intercept is -4. 
This tells us that we need to start at (0,-4). 
Plot that point. 
Since our slope is 3 (3/1), move up 3 and right 1. 

This you will end up at point (1,-1). 
Connect these two points in a straight line, and you have graphed your line.
It will look like this</span>
