$b = 9 {n}^{2} + 7$

$a = 3n + 4$

-----------------------------------------------------------

${a}^{2} = ( {3n + 4})^{2}$

${a}^{2} = 9 {n}^{2} + 24n + 16$

________________________________

$b = 9 {n}^{2} + 7$

$b = 9 {n}^{2} + 24n - 24n + 7 + 9 - 9 \\$

$b = (9 {n}^{2} + 24n + 16) - 24n - 9 - 23 + 23 \\$

$b = (9 {n}^{2} + 24n + 16) - (24n + 32) + 23 \\$

$b = ({3n + 4})^{2} - 8(3n + 4) + 23$

$b = {a}^{2} - 8a + 23$

Thus the correct answer is ( B ) .

Answer:

D. 2 times the distance

Step-by-step explanation:

Practical Math advice: Word Problems usually are tricky so draw, write, and label all you know.

***We want to know how many times farther do the Knicks travel when they play the Los Angeles Lakers compared to the Miami Heat? ***

To do this, we just need to know the distance between the two and divide the bigger by the smaller (think if I told you distance from part A to B is 6 and the distance from part A to C is 3. And then ask you how many times farther the distance to C is from A than B. just divide 6/3 = 2)

1) Note the distance from Madison to Staples (2.8 × 103 miles) and Madison to American A. (1.4 × 103 miles).

We can associate Knicks with Madison, Los Angeles with Staples, and Miami Heat with American A.

2) Now divide 2.8 × 103/(1.4 × 103) = 2
