Answer:
Width is 20cm
Step-by-step explanation:
Step one:
Given data
let the width be x
W= x
L= x+5
P= 90
Step two:
The expression for the perimeter is
P= 2L+2W
90= 2*x+2(x+5)
90= 2x+2x+10
collect like terms
90-10=4x
80= 4x
divide both sides by 4
x= 80/4
x= 20
<h3>
Answer: Point D</h3>
Explanation:
The origin is the center of the grid. This is where the x and y axis meet. The location of this point is (0,0).
Start at the origin and move 5 places to the right. Note how the x coordinate is 5 which tells us how to move left/right. Positive x values mean we go right.
Then we go down 2 spots to arrive at point D. We move down because the y coordinate is negative.
You could also start at (0,0) and go down 2 first, then to the right 5 to also arrive at point D. Convention usually has x going first as (x,y) has x listed first.
