Answer:
L=6 cm l=3
Step-by-step explanation:
x+y=45
L=2l
Big Square Area
L*L=x
Little Square
l*l=y
Substituting
(L*L)+(l*l)=45
(2l*2l)+(l*l)=45
(4l^2)+(l^2)=45
5l^2=45
l^2=45/5
l^2=9
l=sqrt(9)
l=3
L=2(3)
L=6
Step-by-step explanation:
you cannot just put the actual numbers in and calculate ?
and you can't provide the correct problem statement, as it seems.
I assume you mean
an = 3n² - 1
a sequence starts with a1, so, n>=1
a1 = 3×1² - 1 = 3-1 = 2
a2 = 3×2² -1 = 3×4 - 1 = 12 - 1 = 11
a3 = 3×3² - 1 = 3×9 - 1 = 27 - 1 = 26
a4 = 3×4² - 1 = 3×16 - 1 = 48 - 1 = 47
a5 = 3×5² - 1 = 3×25 - 1 = 75 - 1 = 74
there, that is all there is to it. you really needed help with that ?
