Area of a square= lw

A = 2 x 2

A = 4

Area of a triangle= 1/2bh

A = 1/2 1 x 2

A = 1

4 + 1 = 5in.

Step-by-step explanation: (for #2)

A = lw

A = 3 x 2

A = 6

How many liters of water containing 7 grams of salt per liter must be combined with x liters of water which contains y grams [y

iVinArrow [24]

Answer:

$\frac{(2-y)x}{5}\text{ litres}$

Step-by-step explanation:

Let l litre of 7 grams of salt per litre is combined with x litres of water which contains y grams of salt per litre to yield a solution with 2 grams of salt per litre.

Thus,

Salt in l litre + salt in x litre = salt in resultant mixture

7l + xy = 2(l +x)

7l + xy = 2l + 2x

7l - 2l = 2x - xy

5l = x(2-y)

$\implies l =\frac{x(2-y)}{5}$

Hence, $\frac{x(2-y)}{5}$ litres of 7 gram of salt per litre is mixed.

sukhopar [10]

It is not because the figure only has 2 hexagons (top and bottom) but the net has 3. So, your answer is NO.
