Im gonna take an educated guess on this. for the first part only one element has an outershell filled completely. but if they want two elements put chlorine. to lose electrons is probably helium to gain is magnesium. and the last one is lithium and helium because they're small and don't have allot of atomic mass

The equation of a circle is x2 + y2 + Cx + Dy + E = 0. If the radius of the circle is decreased without changing the coordinates
valkas [14]

Answer:

Option E

Step-by-step explanation:

The standard equation of circle is:- (x-h)² + (y-k)² = r²

where (h,k) is center point and r is radius

If radius r is decreased then also (h,k) remains same, only r² increases

Equation given in question is x² + y² + Cx + Dx + E=0

So, C and D will remain same but E will increase

Can someone plz answer B and C
Shkiper50 [21]

B. 
When two lines intersect they form two pairs of opposite angles.
Vertical angles are always congruent, which means that they are equal.
so  m<7 = m<8 or m<3y + 19 = m<5y-29


C. solve for y and measure <7 and <8

 3y + 19 = 5y-29
5y - 3y = 19+29
2y = 48
y = 24

so
5y-29 = 5(24) - 29 = 91
3y + 19 = 3(24) + 19 = 91

so <7 = 180 - 91 = 89
<7 = <8 = 89
