3[10(4^{2} -6+3)] please help!!

471

Step-by-step explanation:

Do what is powered first, and then PEMDAS ( parenthesis, exponents, multiplication, division, addition, subtraction).

It would be 3[10(16) - 6 + 3)] because 4 squared is 16. Next, do the multiplication inside of the brackets, which is 10(16), and that equals 160. Then, finish the math from left to right IN THE BRACKETS do NOT multiply by 3 yet. 160 - 6 + 3 = 157. Now, multiply 3(157), and that equals 471.

Sorry for all caps. People seem to mess up the PEMDAS order a lot, so I'm just trying to make it clear.

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.
