Answer:

55 + 14\sqrt{6}

Step-by-step explanation:

Given

(7 + \sqrt{6} )² = (7 + \sqrt{6} )(7 + \sqrt{6} )

Each term in the second factor is multiplied by each term in the first factor, that is

7(7 + \sqrt{6} ) + \sqrt{6} (7 + \sqrt{6} ) ← distribute both parenthesis

= 49 + 7\sqrt{6} + 7\sqrt{6} + 6 ← collect like terms

= 55 + 14\sqrt{6}

which equation is the point-slope equation of the line that passes through the points (-2,-1) and (7,-4)?
zvonat [6]

Answer:

B (for question 7)

Step-by-step explanation:

To find the slope, we use the equation m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }.

m = (-4+1)/(7+2) = -3/9 = -1/3

Since B is the only option that would give a slope of -1/3, B must be the answer.

(you can use this same method for question 8)
