Answers:
Three points that solve the equation: 
The graph is shown in the attached pictures.
NOTE: The first picture is the graph of the equation along with the plotted points, and the second one shows the work for those three points.
Step-by-step explanation:
1. To graph this equation, an easier way to do it would be to convert to slope-intercept form so we can graph knowing the y-intercept and the slope. Do this by isolating the y on the left side like so:

Remember that slope-intercept form is in y = mx + b format, and that m is the slope and b is the y-intercept. With this information, we know that (0,
) is the y-intercept and
is the slope of this equation. We can plot the point (0,
) on the graph, and then use the slope of
from there to graph other points and form a line. (When I graphed the line, I didn't include these "other points" so it wasn't confusing to locate which points were the three solutions listed.)
2. Points that solve an equation - or solutions - are also points that the line of the equation intersects. So, what we can do is form a table, plug in some x values into the equation, and solve for a y-value. The x and y values will form a point that is on the graph, thus they are solutions. (Please look at the second picture for work and clarification.) After identifying these points, just plot them on the graph and label them (as shown in the first picture).
Step-by-step explanation:
Let the length be L.
Let the breath be B.
So, we are given that
length of a rectangle is 7 inches greater than three times its width .
So, according to the Question,
L = 7+ 3B.
So, we know that:-
Area = Length× Breadth.
So, it will be
B × (7 + 3B) = Area.
So,
3B² + 7 is an expression to represent its area.
Answer:
Step-by-step explanation:
the a square deck as a whole area is 225
side^2 so 15^2
the circles area is 78.54
area of circle formula= pi(r^2)
if you subtract the circle from the squares area you get the outside.
area of deck= 146.46
