Answer:
second is isoscoles, 3rd is a right triangle. I forgot the first
Answer:
D
Step-by-step explanation:
Well, since t = time in air, we already know that it traveled 2 seconds.
H = height in meters, and H = 18
So, after 2 seconds the object is 18m in the air
So, option D
First you multiply
so you will get 6n+6= 18n+29
Then move all "n" on one side of the equation
-23=12n
then divide by 12
the answer should be
n= -1.916
Answer:
18. 28 cm*2
19. 24 m
Step-by-step explanation:
18. length × l = 16
l*2= 16
l = 4
RQ = 4 cm
PR =7cm
Area of parallelogram = b×h
= 7×4
=28cm*2
19. 8 +8 + (6-2) +( 6- 2)
=24 m
