Answer:
<h2>Width of the rectangle is 2</h2>
Step-by-step explanation:
A rectangle can is made up of two right angled triangle as shown.
Since area of a rectangle = 
Area of one of the triangle = 
The length and width of the triangle will be the same as that of the rectangle i.e 5units long and 2units wide
Area of one of the triangle = 
Area of one of the triangle = 5units²
The area of the triangle above will equal one half of a rectangle that is 5 units long and 2 units wide.

ANSWER
The solution is where the two graphs intersect, which is
EXPLANATION
The given system of equations are
and
We need to graph the two equations.
Let us graph
first.
We need at least two points.
You can choose any appropriate value for x and solve for y. Choosing zero makes our working easier. So let us plot the intercepts.
When
So this gives us the ordered pair,
When
we get,
This also gives the ordered pair
We plot these two points and draw a straight line through them to obtain the blue graph in the attachment.
For the second line
We again find the intercepts and plot them.
When
This gives the ordered pair
Also, when
then we have,
Then we again have the ordered pair,
We plot these two points on the same graph sheet to obtain the red graph above.
The intersection of the two lines is
You will get good grades so don't worry much.
Answer:
length = 18 ft
Step-by-step explanation:
Let w = width
L = w+7
Area = l*w
198 = (w+7) (w)
Distribute
198 = w^2 +7w
Subtract 198 from each side
0 = w^2 +7w -198
Factor
What 2 numbers multiply to -198 and add to 7
18* -11 = -198
18+-11 = 7
0=(w+18) (w-11)
Using the zero product property
w+18 =0 w-11=0
w= -18 w=11
We cannot have negative width so w=11
We want the length
l = w+7
l = 11+7 = 18
