Answer:

260

20

Step-by-step explanation:

speed of plane= p

speed of wind =w

  • (p+w)*3=840
  • p+w=840/3=280

and

  • (p-w)*3.5=840
  • p-w= 840/3.5= 240

added up the 2 equations we get:

  • 2p= 280+240
  • p=260 mph

then

  • w= 20 mph

Can someone help me please
Tasya [4]

Answer:

  Square

Step-by-step explanation:

The length of AB is (a+b)-a = b. The length of BC is b-0 = b. So, adjacent sides are the same length. AB has a constant y-value, so is horizontal. BC has a constant x-value, so is vertical.

A figure with horizontal and vertical sides of the same length is a square.
