<span>Arrange the first row arbitrarily: 1 2 3 4.
Then there is only one option to begin the next row: 3.
The remaining row must be 4 1 2.
This leaves no options for beginning the third row (1 and 3 are in the same column, and 2 and 4 share the diagonal).</span>

A window frame has a length of (5x+3) inches an a width of (x+6) inches. The area of the glass in the window is (4x^2+26x+15) sq

boyakko [2]

ANSWER

the area of the trim around the glass in the window is option ( D)

i.e (x²+7x+3)

REASON

As given in the question

A window frame has a length of (5x+3) inches an a width of (x+6) inches.

As the shape of the window in the form of rectangle.

Formula

Area of the rectangle = length × breadth

put the value in the above equation

we get

Area of window = (5x+3)× ( x + 6)

= 5x² + 33x + 18 inches²

As given in the question

The area of the glass in the window is (4x²+26x+15) square inches.

Area trim around the glass in the window = area of the window - area of the glass.

put the value

we get

= ( 5x² + 33x + 18 ) - ( 4x²+26x+15)

= 1x²+ 7x + 3 inches²

therefore the correct option is (D)

Hence proved

Write the following as an expression: How much water do I need to add to l liters of pure alcohol to obtain a solution of 45% al

Grace [21]

Answer:

13/9l or 1 4/9 l

Step-by-step explanation:

quantity of alcohol = l liters

we need to made solution of having 45% alcohol by adding water.

45% alcohol means whatever id the total quantity of solution there is 45% alcohol.

Let the total quantity of solution be x.(

then

quantity of alcohol in terms of x = 45% of x = 45/100 x

but we know that quantity of alcohol = l liters

45/100 x = l

x = 100/45 l

Thus, total quantity of solution is 100/45 l,

but in it there is l liters of alcohol.

to find quantity of water we need to subtract quantity of alcohol from total quantity of solution

quantity of water in the solution = 100l/45 - l = (100l - 45l)/45 = 65l/45

quantity of water in the solution = 13/9l = 1 4/9 l -------->answer.

Thus, 1 4/9 liters of water needs to be added to l liters of alcohol to make a solution of 45% alcohol.
