pls help guys really fast and with process pls ​

Answer 1

Answer:

a)20m/s

b)33⅓%=100/3%=0.3333....

c)2(3-2x)=13

6-4x=13

-4x=13-6

-4x=7

x=-7/4

d)area of parallelogram =base ×height =8×4.5=36cm²

hope it helps you and don't forget to follow mè

Answer 2

Case 1:

Speed = 72 km/h

Speed = m/s = 72×5/18 m/s = 20 m/s

Case 2:

⇒ 2(3-2x) = 13

⇒ 6-4x = 13

⇒ -4x = 13-6

⇒ -4x = 7

⇒ x = -7/4

Case 3:

Base of Parallelogram = 8cm

Height of Parallelogram = 4.5cm

Area of the Parallelogram = bh

⇒ 8cm×4.5cm

⇒ 36cm^2

Therefore, the area of the parallelogram is 36cm^2

Hope this helps you.
