The figure shows three quadrilaterals on a coordinate grid: see image
FrozenT [24]

Hello!

The statement that is true about the three quadrilaterals is the first one:

\boxed{ \bf D~and~E~are~similar~but~not~congruent.}

____________________________________________________________

Option #2 is incorrect because although E and F are similar, they are not congruent. They do not have the same size.

Option #3 is also incorrect because, again, D and E are similar, but they are not congruent.

Option #4 is not correct because it says that "F and D are similar but not congruent." This is not true since they are the same shape and size. Only their orientation is different, which makes them congruent.

Xian and his cousin kai both collect stamps. Xian has 52 stamps, and kai has 76 stamps. The boys recently joined different stamp
Darya [45]

<em><u>Explanation</u></em>

Xian has 52 stamps and Kai has 76 stamps.

Xian's club will send him 16 new stamps per month and Kai's club will send him 12 new stamps per month.

Suppose, Xian and Kai will have the same number of stamps after x months.

So, the total number of new stamps for Xian = 16x and the total number of new stamps for Kai = 12x

So, the equation will be......

52+16x=76+12x\\ \\ 16x-12x=76-52\\ \\ 4x= 24\\ \\ x=6

Thus, Xian and Kai will have the same number of stamps after 6 months.

The number of stamps for each of them will be: 52+16(6)=148
