Answer:
Step-by-step explanation:
slope is rise/run or change in y, over change in x
Therefore, slope = (7-8)/ (-4 +8)
= -1/4
Answer:
352 m
Step-by-step explanation:
The area of a trapeze is (the biggest base + the smallest base) × height / 2
The area from rectangles are side a × side b
Trapeze: (6+12)×4/2 = 36
Rectangles: 5 × 10 = 50
6 × 10 = 60
12 × 10 = 120
There are two trapeze andtwo rectangles with the samesize, so you double their area:
2×36 + 2 × 50 + 60 + 120 = 352 m
8.5 is the nearest one
square root of 72 is about 8.48
rounding to the nearest tenth gives you 8.5
