The answer is b and the reason for that is because for the points you are basically dividing by 2 so it’s dilated by a factor of 2 and it’s reflected across the x-axis because the new shape is not beside it is ontop and if you would have reflected it by the y-axis the new shape would be across is it’s like if you bend the graph hotdog style because the line that’s in the middle is the y-axis it will give a yaxis reflection but if you bend it hamburger style because the line across is xaxis it will give you a xaxis reflection:)) hope I helped

Answer:

The distance between the pirate and the treasure can be found from the following relationship between ΔEAF and ΔABC;

$\overline{AE}$ / $\overline{AB}$ = $\overline{FA}$ / $\overline{AC}$ = $\overline{EF}$ / $\overline{BC}$

Step-by-step explanation:

From the question diagram, we have two triangles, ΔEAF and ΔABC;

The ratio of the lengths of the sides $\overline{AE}$ / $\overline{AB}$ = $\overline{FA}$ / $\overline{AC}$

∠EAF and ∠BAC are vertical angles, therefore ∠EAF = ∠BAC

Therefore, ΔEAF and ΔABC are similar triangles by Side-Angle-Side, SAS, rule of similarity which states that two triangles that have ratios of a pair of their corresponding sides and the two sides also form equal angles within each triangle, then the two triangles are similar

Therefore, the ratio of the each pair of corresponding sides of the two triangles are equal

We have;

$\overline{AE}$ / $\overline{AB}$ = $\overline{FA}$ / $\overline{AC}$ = 50 ft. /(100 ft.) = $\overline{EF}$ / $\overline{BC}$ = $\overline{EF}$ /120 ft.

$\overline{EF}$ = 120 ft. × 50 ft./(100 ft.) = 60 ft.

$\overline{EF}$ = 60 ft.

The distance between the pirate and the treasure, $\overline{EF}$ = 60 ft.

The living room in the house has an area off 244 square feet and a width of 14 feet what is the length of the room

xxTIMURxx [149]

Answer:

Step-by-step explanation:

So if its 224 square feet and the width if 14 feet the length should be 14 also I think lol Here , imagine a square put 224 inside it for the area , then put down 14 on top and bottom because its the width , multiple 14×14=56+140=196+14=210+14=224 And the last 14's are the length which u have to add Im not sure if that made any sence lol but I hope it did .
