Answer:
10cm
Step-by-step explanation:
The formula for perimeter is:
Let the width of the rectangle be x then the length would be...
3+x
Now, let's plug these values into the equation and solve. (Note we are also given perimeter is 34 cm):
And since the length is x+3 then it is...
x+3=7+3=10cm
<h3>Two Answers: <u>x = 2 and x = 10</u></h3>
========================================================
Explanation:
Draw a horizontal line through 10 on the y axis. This is because R(x) = 10 is the same as y = 10. The output of the function is the y value.
See the diagram below.
The horizontal line crosses the parabola at two locations. From those points, draw a vertical line straight down to the x axis. Note how we land at x = 2 and x = 10. This means that R(2) = 10 and R(10) = 10.
