Quizz of basics (By Nihal)

The factorisation of 12x+36 is

• 12(x+3)

• 12(3x)

• 12(3x+1)

• x(12+36x)

On factorising 14pq + 35pqr, we get:

• pq(14+35r)

• p(14q+35qr)

• q(14p+35pr)

• 7pq(2+5r)

-3-5 =

• -14

• -6

• -7

• -8

If $\frac{9}{5}x\ =\ \frac{18}{5}$  , then x = ______

^x/₄ = 2

• x = 8
• x = 2
• x = 0.5
• x = 6

Multiplicative inverse or Reciprocal of 2 ⁄ 3 is ______

• 2 ⁄ 3

• 0 / 3

• 3 ⁄ 2

• 1

n+2=-14-n

• 6
• 8
• -8

Set up an equation for the following: When I subtracted 9 from twice a number, the result was 11.

• x – 9 = 11

• 9 – 2x = 11

• 2x – 9 = 11

Solve:-

4(m+3)=18

• 2/3

• 3/2

• 6/2

• 3/5

For a number of p/q form(p,q are integers) to be a rational number, the DENOMINATOR

• should be 0

• should never be 0
