Which expression is equivalent to 10a + 6? A. 10(a + 3)
B. 2(5a + 3)
C. 5(5a + 1)
D. 10(a + 1)

The answer is: 2(5a + 3)

hope this helps :)

B. 2(5a + 3)

Step-by-step explanation:

Using the distributive property, we know that we can distribute to polynomial within parenthesis. So, following this, we can multiple 2*5a and 2*3. This gives us the expression, 10a+6. Showing that these two expressions are equivalent.

Additionally, the expression 2(5a+3) is an example of factoring. The GCF, 2, was factored out of the original expression 10a+6. Since 2(5a+3) is a factored form of 10a+6, they must be equivalent.

step-by-step explanation:

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!
