<h2><u>Direct answer</u> :</h2>

Width of the enlarged photograph = 14 cm

<h2><u>Steps to derive the correct answer</u> :</h2>

Length of a small photograph = 6 cm

Width of a small photograph = 4 cm

Length of the photograph when enlarged = 21 cm

Let the width of the photograph when enlarged be x.

Which means :

= \tt 4 : 6 : : x : 21

=\tt  \frac{4}{6}  =  \frac{x}{21}

=\tt 4 \times 21 = 6 \times x

=\tt 84 = 6x

=\tt x =  \frac{84}{6}

=\tt x = 14

Thus, the value of x = 14

Therefore, the width of the enlarged photograph = <u>14 cm</u>

If you graph a system of linear inequalities that have no overlap, what can you determine from the slopes of the inequalities?
NISA [10]
I have found the options elsewhere and they are as follows:

the slopes must be positive

the slopes must be negative

their slopes are equal

the slopes are opposite reciprocals.


From the choices, I think the correct answer would that their slopes are equal since they are parallel lines and never intersect.

The area of a square garden is 128m sqared.how long is the diagonal
weqwewe [10]

The area of a square is  (side)².
If the area is  128m², then the side is  (√128) meters. (That's 8√2.)

The diagonal is the hypotenuse of the right triangle you get
if you slice the square in half along the diagonal.  Its length is
given in the words of Old Pythagoras:

               c² = a² + b²

'a' and 'b' are sides of the square, so

             c² = (√128)² + (√128)²

                 =    2 (√128)²

              c  =  √ (2 x 128)  =  √256  =  16 meters .
