Choose one of the factors of x^3 + 343.
answer
a. none of the above
b. x^2 + 7x + 49
c. x – 7
d. x^2 – 14x + 49

First, note that Then use the formula for the sum of perfect cubes:

Therefore,

The quadratic trinomial couldn't be factored anymore, so the expression has two factors and

correct choice is A.

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6

it would more likely be bald eagle because its has more in the box so about 75%.
