Levart [38]

Answer:

$\boxed{\sf -2}$

Step-by-step explanation:

$\sf Evaluate \: - {x}^{2} - 4x - 6 \: where \: x = - 2: \\ \sf \implies - {x}^{2} - 4x - 6 = - {( - 2)}^{2} - 4( - 2) - 6 \\ \\ \sf {( - 2)}^{2} = 4 : \\ \sf \implies - \boxed{ \sf 4} - 4( - 2) - 6 \\ \\ \sf - 4( - 2) = 8 : \\ \sf \implies - 4 + \boxed{ \sf 8} - 6 \\ \\ \sf - 4 + 8 - 6 = 8 - (4 + 6) : \\ \sf \implies 8 - (4 + 6) \\ \\ \sf 4 + 6 = 10 : \\ \sf \implies 8 - \boxed{ \sf 10} \\ \\ \sf \implies - 2$

Answer:

252

Step-by-step explanation:

Types of main courses available = 9

Types of drinks offered = 7

Types of deserts = 4

Number of different meals consisting of a main course, a drink and a desert offered

Using the combination rule :

9C1 * 7C1 * 4C1

nCr = n! ÷ (n-r)!r!

So using calculator we obtain :

9 * 7 * 4 = 252

Ned help on this plz hurry

Answer:

Option A will be correct.

Step-by-step explanation:

Given that polygon ABCD and polygon JKLM are similar.

Therefore, the corresponding sides of the two similar polygons will be in the same ratio.

Hence, $\frac{AB}{JK} = \frac{BC}{KL} = \frac{CD}{LM} = \frac{DA}{MJ}$

Hence, we can write $\frac{3}{x} = \frac{6}{59}$

⇒ $x = \frac{59}{2} = 29.5$ {Since given that CD = 3, DA = 6, LM = x and MJ = 59}

Therefore, option A will be correct. ( Answer )
