Answer:
use the formula a^3+b^3= (a+b)-3ab(a+b)
in above question assume (a+b) as a and 1 as b
later in (a+b+1) take (a+b) as a and 1 as b
and use the formula (a+b)^2 = a^2+2ab+b^2
Answer:
686
Step-by-step explanation:
528+374 = 902 - 216 = 686
It should be 125 as
BC=100
and it's four times the length of AB then
100/4=25
then 100+25=125
I hope this helps
