iv) the product of (-1) and 8 is 8​

Answer 1

Answer:

i)

Step-by-step explanation:

because 5+7=12

10<12

Answer 2

(i) The sum of 5 and 7 is 12 which is always greater than 10 anywhere, anytime, anyway. Hence the sentence is a statement. $\quad$

(ii) The squares of even numbers only, in fact, are even numbers, so that the squares of odd numbers are not even. Hence the sentence is not a statement.

(iii) Not necessarily, but can be. The sentence holds true only if all the quadrilaterals are rhombuses. However, the sentence is not a statement.

(iv) Absolutely wrong, and hence the sentence is not a statement.

Therefore, the sentence (i) is the real statement among all.
