A square and a rectangle have equal perimeters. The length of a side of the square is 4x – 1. The length of the rectangle is 2x + 1 and the width is 2x. Write and solve an equation to find x.

1.Peter works as a delivery person for a bike shipping company. The graph shows a linear model for his delivery times on different days.  

Peter’s Deliveries

(a)What is the equation of the line, first written in point-slope form and then written in slope-intercept form? Show how you determined the equation.

(b)Based on the linear model, predict how long it initially took Peter to deliver his packages (y-intercept). Approximately how much did his delivery time decrease per day (slope)? Complete sentences

Step-by-step explanation:

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
