Answer:
4cm + 2.8cm +4cm = 10.8 cm
Step-by-step explanation:
Formula Perimeter is A+B+C
First, you need to change the 28 mm to cm (move decimal once space to the left making 28mm to 2.8 cm)
Next, add all your sides that are now in the same format of cm
4 +2.8 +4=10.8 cm
2. Use the equation y = 4x to answer the questions. Graph y = 4x.
What is the slope of y = 4x and what does this mean?
Part 1
For the given equation complete the table:
1) when x=0, then
2) when y=0, then
3) when x=2, then
4) when x=4, then
Therefore, the table is
With these data you can plot the graph of the function (see 1st diagram).
Part 2
The graph of the function y=4x is represented in the second diagram. The slope of the line is m=4.
