Answer:
c) (x + 2)(x + 2i)(x - 2i)
Step-by-step explanation:
x^3 + 2x^2 + 4x + 8
= (x^3 + 2x^2) + (4x + 8)
= x^2( x + 2) + 4(x + 2)
= (x + 2)(x^2 + 4)
= (x + 2)(x^2 - 4i^2) ---------------------------->(i^2 = -1)
= (x + 2)(x + 2i)(x - 2i)
Answer choice D, A,B, and C both equal 3.
Step-by-step explanation:
okay
I think you should use the method of tan 30
and then find x by using pythagorean theorem
To the nearest tenth: 3,333,330
To the nearest hundred: 3,333,300
To the nearest thousand: 3,333,000
To the nearest ten thousand: 3,330,000
To the nearest hundred thousand: 3,300,000
To the nearest million: 3,000,000
Hope that helps :)
