Hi May I know how to solve this with step by step explanation please
trapecia [35]

Answer:

13.33 cm

Step-by-step explanation:

Given, ratio of volumes v ÷ V = 8 ÷ 27

This ratio is applicable to heights of same containers, as the volume is directly proportional with height (V=Ah, A- base, h- height)

So we have:

  • h ÷ H = 8 ÷ 27

and

  • H=45 cm

Then,

  • h ÷ 45 = 8 ÷ 27
  • h = 45 × 8/27
  • h = 40/3 = 13.33 cm

(Picture) MULTIPLYING MONOMIALS AND BINOMIALS
Sauron [17]

Answer:

Option C is correct, i.e. 2x² +7x -4.

Step-by-step explanation:

Given is (2x-1)(x+4)

Applying FOIL method:-

F- multiply First two, O- multiply Outer two, I- multiply Inner two, L- multiply Last two.

So, (2x-1)(x+4) = 2x*x +2x*4 -1*x -1*4

(2x-1)(x+4) = 2x² +8x -1x -4

(2x-1)(x+4) = 2x² +7x -4

Hence, option C is correct, i.e. (2x-1)(x+4) = 2x² +7x -4.
