6. explain the difference between “4 times the sum of x and y” and “the sum of 4 times x and y.

The difference can be elaborated by the following equation

"4 times the sum of x and y"

 and "sum of 4 times x and y"

Step-by-step explanation:

In the first condition the two terms x and y are summed up first then multiplied by 4. First add two digits then multiplexed..

In second case the 4 times of x is first calculated then added with y.

Note:

First condition will always be greater than second because in first condition both the digits are multiplied with 4 but in second only second is multiplied with 4.

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.

answer:   rotate 270° clockwise about (7, 1) and reflect across the line x = 7
