Answer:
4x^2+12x+9
Step-by-step explanation:
(2x+3)(2x+3)
Multiply 2x by 2x first.
then 2x by 3
and then repeat that step and you add like terms
then recieve your answer.

uhm how do i help?
Answer:
b
Step-by-step explanation:
given =
(a) is true
consider the numerical example
= ⇔ =
(b) is not true ( cross- multiply the original equation ) gives
mr = ab ⇒ (c) is true
(d) is true
using result from (c) divide both sides by a and m
= ⇒ =
U need to subtract 880.00 by 16.65 then add to that answer 5.35
Answer: Simple cubic=0.39nm
Face centred cubic
=0.55nm
Body centered cubic
=0.45nm
Diamond lattice= 0.9nm
Step-by-step explanation: The lattice constant (a)
for SC=2*r
Fcc=4*r/√2
Bcc= 4*r/√3
Diamond lattice=8*r/√3
Here,
r is the atomic radius measured in nm
r = 1.95Å * 1nm/10Å
=0.195nm
Now let's calculate (a)
SC = 2*r = 2*0.195 nm=0.39nm
Fcc = 4*r/√2 =4*0.195nm/√2
= 0.55nm
Bcc = 4*r/√3 =4*0.195nm/√3
= 0.45nm
Diamond lattice = 8*r/√3
=8*0.195nm/√3
= 0.9nm
