Polygons are
triangle, trapezoid, triangle, parallelogram, rectangle and parallelogram
The area of triangles = 1/2 * base * haight.
Area of the parallelograms = height * base.
Area of rectangle= width * length
Area of trapezoid = 1/2 * (a + b) * height where a and b are the opposite parallel sides
The perimeters = sum of the sides of the polygons.
you must substitute x in the equation given :)
examples:
when x is -2
therefore, y = 2(-2) + 3
y = -1
when x is 0
therefore, y = 2(0) + 3
y = 3
when x is 1
therefore, y = 2(1) + 3
y = 5
when x is 3
therefore, y = 2(3) + 3
y = 9
for (b) you only have to plot based on the table ;)
hope this helps
I'm guessing 1 and 4, but I'm not sure.
Answer:
80 Miles
Step-by-step explanation:
If you convert 15 minutes to hours, you get .25 hours. Then, you use that number and multiply it by 320 to get your answer; 80 miles.
