Answer:
7n^3 + 6
Step-by-step explanation:
(4 + 2n^3) + (5n^3 + 2) =
= 2n^3 + 5n^3 + 4 + 2
= 7n^3 + 6
Answer:
sqrt(5)/29
Step-by-step explanation:
1/(5 + 3sqrt(5))
= 1/(5 + 3sqrt(5)) x sqrt(5)/sqrt(5)
= sqrt(5)/(5 + 3 x 8)
= sqrt(5)/ 29
When the transverse axis is horizontal, a hyperbola centered at (h,k) has formula (x-h)^2/a^2-(y-k)^2/b^2=1. Plug in h=2, k=1, the formula is (x-2)^2/a^2-(y-1)^2/b^2=1 for some a,b. If the transverse axis is vertical, the formula is (y-h)^2/a^2-(x-k)^2/b^2=1, and (y-2)^2/a^2-(x-1)^2/b^2=1 in our case.
Answer:
<u>7 groups of 8 = 6 groups of 8 plus 1 group of 8</u>
Step-by-step explanation:
1. Let's review the information given to answer the question correctly:
7 groups of 8 = 6 groups of 8 plus ?
2. Let's answer the question, this way:
How much are 7 groups of 8? 56 = 7 * 8
How much are 6 groups of 8? 48 = 6 * 8
What is the difference between 7 groups of 8 and 6 groups of 8?
(7 - 6 ) * 8 = 1 * 8
Therefore,
<u>7 groups of 8 = 6 groups of 8 plus 1 group of 8</u>
