Answer:
idk its hard to me too
Step-by-step explanation:
slope = m=(y2-y1)/(x2-x1)
m= (4-5)/(1-(-2))
m= -1/(1+2)
m=-1/3
Choice C
Because a triangle's angles need to equal 180, you can subtract 100(30+70) and you will get 80. So 80 will be your third angle.
Answer:
67 ½ units³ or 135/2 units³
Step-by-step explanation:
Volume = Base area × height
In case:
width is 6 the height is 4 1/2 and the length is 2 1/2
2 ½ = 5/2
4 ½ = 9/2
Volume = (6 × 5/2) × 9/2
= 15 × 9/2
= 135/2
= 67 ½ units³
