Explanation

-9×-9=81

So B is correct

Explanation

The Base is the one or the number that is repeatedly multiplied by itself. -6 is the base, and the 5 is the exponent.

Explanation

 √2, √3, √5, and so on are some examples of irrational numbers as they cannot be expressed in the form of p ⁄ q

Explanation

Explanation

Step 1: Multiply the coefficient of the first term by the constant term i.e. (6 x 1) = 6

Step 2: Find the two factors of 6  such that whose sum equals to the coefficient of the middle term, i.e. -5.

Thus, the factors are -3 and -2 as,

-3 × (-2) = 6 (Product)

-3 + (-2) = -5 (Sum)

The polynomial  after splitting the middle term by using the two factors, -3 and -2 can be written as

x² - 3x - 2x + 6 = 0    

x(x-3) -2(x-3) = 0

(x-3)(x-2) = 0 

Explanation

Simple mathematics question … (solve for X)

12/22 = 30/X

12X = 22 * 30

12X = 660

X = 55

Explanation

= (5/100)*75

= (5*75)/100

= 375/100

= 3.75

Explanation

Annual income by salary 2200×12=26400.

Explanation

convert in m/s

90km×1000m=90000m

1hr=3600sec

9000m÷3600sec÷35m/s

35m/s×60÷2100

35m/s×2100÷52500

52500m÷1000m=52.5km

Explanation

A man stands facing West.

He turns 45° in the clockwise direction then another 180° in the same direction and then 270° in the anticlockwise direction.

Therefore, the man is now facing the southwest direction.

Hence, the correct answer is "South-West​".
