Which polynomial is in standard form?
A) 3x6 + 4x4 + 6x5 + 7x2 − 8x
B) 5x6 + 3x4 + 6x3 + 5x2 − 2x
C) 5 + 3x + 6x2 + 5x3 − 3x4
D) 6x + 3x4 + 4x6 + 5x8 + 2

B.  5x6 + 3x4 + 6x3 + 5x2 − 2x

Step-by-step explanation:

A polynomial is in standard form when when its term of the highest degree is first, it's term of second highest is 2nd, and so on.

So, in our case, we can take a look at the exponents in each row.

A would be 6, 4, 5,2, and 1. That would not be correct since it is not from greatest to least. With the 6 being the highest and 5th being the 3rd highest.

C would be 0, 1, 2, 3, 4. That would not be correct since that is from least to greatest.

D. would be 1, 4, 6, 8 and 0. That again would not be correct since its numbers are going from least to greatest to least.

if gloria has "carry over" minutes, (that is, any minutes paid for but not used in a month can be applied to her payment for minutes in the next month,) her total usage for the three months is: total minutes = 320 + 243 + 489 = 1052 minutes number of 200 minute blocks = 1052/200 = 5 r52 (that is 5 with a remainder of 52) rounding up the number of 200 minute blocks gives her usage for the three months as 6 blocks. the cost for six blocks is 6 x $25 = $150 she also has 200 - 52 or 148 carry over minutes if gloria pays each month and unused minutes are lost, applying the rounding up procedure to each month gives: first month usage of 320 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 second month usage of 243 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 third month usage of 489 minutes rounds up to 3 blocks of 200 minutes for a payment of 3 x $25 = $75 total payments for the three months are $50 + $50 + $75 = $175 get the plan with carry over minutes!
