Answer:

The trick to this problem is that first you have to subtract the digits and then add them. For example:

6 and 4, if we subtract them, we get 2 and if we add them, we get 10, therefore the answer is 210.

9 and 2, if we subtract them, we get 7 and if we add them, we get 11, therefore the answer is 711.

This works for the rest of the numbers as well and we can use it for the unknown problem

8 - 3 = 5

8 + 3 = 11

Therefore, the answer is 511

Answer:

\fbox{511}

<h3>Explanation:</h3>

6+4=(6 - 4)(6 + 4) = 210

9+2=(9  - 2)(9 + 2) = 711

8+5=(8 - 5)(8 + 5) = 313

3+2=(3 - 2)(3 + 2) = 15

following the same pattern,

8+3=(8 - 3)(8 + 3) = 511

mars1129 [50]

Answer:

a=22.5\ units

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is equal

so

In this problem

If polygon RSUPE is similar to polygon KQUIC

then

\frac{RS}{KQ}=\frac{RE}{KC}

substitutes the values and solve for a

\frac{a+2}{14}=\frac{17.5}{10}\\ \\10a+20=14*17.5\\ \\10a=245-20\\ \\a=225/10\\ \\a=22.5\ units
