Adding 'like' square root terms is like stacking boxes of the same size. For example, 2√2 + 4√2 + 7√2 = . 1 . 13
2.13√2
3. 26
4. 26√2

  2.  13√2

Step-by-step explanation:

You can consider the radical as though it were some (non-numeric) symbol.

Using Ф for √2, this becomes ...

  2Ф +4Ф +7Ф = (2+4+7)Ф = 13Ф

Using √2 for Ф, this becomes ...

  = 13√2

In short, do not be intimidated by the radical expression. Treat it as you would any other symbol for purposes of collecting terms. (Of course, you can only combine "like" radicals.)

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.

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
