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.

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
