Answer:

see explanation

Step-by-step explanation:

take the square root of both sides

step 4 : x + 4 = ± $\sqrt{11}$ ( subtract 4 from both sides )

step 5 : x = - 4 ± $\sqrt{11}$

step 6 : x = - 4 - $\sqrt{11}$ , x = - 4 + $\sqrt{11}$

Answer:

1) Change the length of side AB to 2 feet

Step-by-step explanation:

Given that both structures are similar, it follows that the ratio of their corresponding lengths are equal.

To find out what should be the correct length of AB that she should change to, set up the proportion showing the ratio of 2 corresponding lengths of both structures. Thus:

$\frac{PR}{AC} = \frac{PQ}{AB}$
