Answer 1

Step-by-step explanation:

Answer

1) the element with atomic number(Z) 17 & mass number (A) 35 is chlorine =

2) the element with atomic number(Z) 92 & mass number (A)233 is uranium =

3) the element with atomic number(Z) 4 & mass number (A) 9 is berellium =

Answer 2

We Know that ,

$x ^{3} + y ^{3} + z ^{3} = 3xyz$

[tex] - 12 ^{3} + ( - 15 ^{3} ) + ( - 13 ^{3} ) = 3 \times ( - 12)( - 15)( - 13)

= -12 x -15 x -13

= -2340 answer
