Answer:
the second one four fifth times 20
Step-by-step explanation:
4/5×22.01=17.68 which is approximately equal with 4/5×20=16.
Perimeter and area are two important and fundamental mathematical topics. They help you to quantify physical space and also provide a foundation for more advanced mathematics found in algebra, trigonometry, and calculus. Perimeter is a measurement of the distance around a shape and area that gives us an idea of how much surface the shape covers. The perimeter of a two-dimensional shape is the distance around the shape. You can think of wrapping a string around a triangle. The length of this string would be the perimeter of the triangle. Or walking around the outside of a park, you walk the distance of the park’s perimeter. Some people find it useful to think of “peRIMeter” because the edge of an object is its rim and peRIMeter has the word “rim” in it.

Answer:
slope = - 4
Step-by-step explanation:
Calculate the slope m using the slope formula and any 2 ordered pairs from the table.
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 2, 8) and (x₂, y₂ ) = (- 1, 4) ← 2 points from the table
m = = = - 4
