Which long division problem can be used to prove the formula for factoring the difference of two perfect cubes? a-b) a² + ab +b²
o a+b) a² - ab +b²
a+b) a^3 +0a^2b+0ab^2 – b^3
a-b)a^3 +0a^2b+0ab^2 - b^3

we know that

applying the law of sines

°

so

∠j=18°

∠k=29°

∠l=180-(18+29)=133°

the answer part a) is

the measure of angle k is  ≈29°

part b)  the measure of angle k could also be

(180-29)=151°

so

∠j=18°

∠k=151°

∠l=180-(18+151)=11°

the answer part b) is

the measure of angle k could also be 151°

hope i'm right lol

answer: 8

step-by-step explanation: if you add the possibilities 5 different flavor and 3 different sizes 5+3=8
