Answer:

Step-by-step explanation:

2(4x - 3) - 3(5 - x) <em>use the distributive property </em><em>a(b + c) = ab + ac</em>

= (2)(4x) + (2)(-3) + (-3)(5) + (-3)(-x)

= 8x - 6 - 15 + 3x <em>combine like terms</em>

= (8x + 3x) + (-6 - 15)

= 11x - 21

denis-greek [22]

Answer:

Option B

Step-by-step explanation:

Here we have to apply " combination and permutation. " It is given that the drama club had to choose three booths from a selection of 9, considering the possible ways to choose so. This is a perfect example of combination. In nCr, n corresponds to 9, respectively r corresponds to 3.

$\mathrm{n\:choose\:r},\\nCr=\frac{n!}{r!\left(n-r\right)!},\\\\\frac{9!}{3!\left(9-3\right)!} =\\\frac{9!}{3!\cdot \:6!} =\\\\\frac{9\cdot \:8\cdot \:7}{3!} =\\\frac{504}{6} =\\\\84\\\\Solution = Option B$
