Um I think it is 2,1 count over 2 then go up1
170 ≤ 75 + 12.5v (third one)
(4/2)^2*3.4*4
2^2*3.4*4
4*3.4*4
13.6*4
54.4
(4/2)^2*3.4*4
2^2*3.4*4
4*1.7*4
6.8*4
27.2
the answer is 54.4 or the answer is 27.2, i can't quite figure it out but those are my best guesses
Answer:
the number of protons identifies what element it is, since it has 35 protons it is Bromine
number of protons=atomic number
Answer:
r=20
Step-by-step explanation:
since the angle and sum of a straight line is equal to 180, you structure an equation:
180=105+(4r-5)
solve for r
180=100+4r
80=4r
20=r
check answer
4r-5 4(20)-5
80-5
75+105=180
