Needme 1.)a rectangle has a length that is 8 less than its width, w. the perimeter is 52. which equation can be used to determine its width? 8-w=52 2(w-8)+2w=52 (w-8)+w=52 2(8-w)+2w=52 2.)garrett is creating a table to model the speed of a canoe in a river. he knows that the canoe travels at 4 mph in still water. what does x represent in garrett’s table? a. speed of current in river b. speed of canoe upstream c. time of trip d. distance traveled

1. 2(w-8)+2w=52.

2.A. speed of current in river.

Step-by-step explanation:

1. Given

Width of rectangle = w

Length of rectangle is 8 less than its width

Therefore, the length of rectangle =w-8

The perimeter of rectangle= 52

We know that perimeter of rectangle =

By using thi formula

Substitute the value of length, width and perimeter we get

52= 2

By simplification we getb

Hence,  the equation can be used to determine its width

.

2.Garrett is creating a table to model the speed of a canoe in a river

Speed of canoe in still water= 4m\h

From table

Downstream Speed of canoe =

Upstream speed of Canoe=

We know that

Downstream speed of Canoe= speed of Canoe in still water + speed of current in river

By comparing two value of downstream

speed of Canoe in still water=4 m\h ( given )

Then x represent the speed of current in river.

Hence, option A is correct answer.
