$\bf \stackrel{eg}{5x+8}-\stackrel{fg}{3x}=\stackrel{ef}{6x-4}\implies2x+8=6x-4\implies 12=4x
\\\\\\
\cfrac{12}{4}=x\implies 3=x\qquad \qquad \stackrel{ef}{6(3)-4}$

and surely you know how much that is.

Lorico [155]

Answer:

Step-by-step explanation:

We have been given that dimensions of original photo are 4 inches by 6 inches. We want the photo on the poster to be of dimensions 3 feet by 4 1/2 feet.

First of all we will convert dimensions of poster from feet to inches.

$3\text{ feet}=3\times 12 \text{ inches}=36\text{ inches}$

$4\frac{1}{2}\text{ feet}=4.5\times 12 \text{ inches}=54\text{ inches}$

Now let us compare sides of our original photo with corresponding sides of poster.

$\frac{36}{4} =9$

Now let us compare the second pair of corresponding sides.

$\frac{54}{6} =9$

We have seen that sides of poster are 9 times the sides of our original photo, therefore, the scale factor of this dilation is 9.
