Question 6

Question 7

The width is 2x.

Step-by-step explanation:

                                           Question 6)

Expand

solving to the expand

so the expression becomes

adding similar elements: 20a+2a=22a

Hence,

                                                  Question 7)

Given

Using the formula

width = Area/Length

                           ∵

Therefore, the width is 2x.

x + 4/7

step-by-step explanation:

use cymath

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
