Answer:

0, -1

Step-by-step explanation:

zeros occur when 2x^6+2x^5=0

the first way for this to happen would be to set x to 0. both terms would become zero.

the second way is x = -1

first term becomes 2

second becomes -2

these add to zero

Answer:

Step-by-step explanation:

$\frac{b}{-3}+4< 13$

Step 1: Subtract 4 form both sides

Step 2: Multiply both sides by (-3). when we are multiplying by (-3) the < will change to >.

$\frac{b}{-3}+4-4 9*-3\\\\b > -27$

21x =7?<br> A. x=3<br> B. None of these <br> C. x=147<br> D. x=28

Varvara68 [4.7K]

Answer: B

Step-by-step explanation:

To isolate x, you divide both sides by 21

21x=7

$\frac{21x}{21}=\frac{7}{21}$

x = 7/21

Simplify by dividing both the numerator and denominator by 7

x = 1/3

Since, 1/3 is not an option, B is the correct answer

Simplify x to the 1/3 power (x to the 1/2 power + 2x to the 2 power )

OverLord2011 [107]

Answer:

x^(5/6) + 4(x^(7/3))

Step-by-step explanation:

Simplify x to the 1/3 power MULTIPLIED BY (x to the 1/2 power + 2x to the 2 power )

Simplify x^(1/3) × (x^(1/2) + (2x)^2)

= x^(1/3)(x^(1/2)) + x^(1/3)((2x)^2)

= x^(1/3+1/2) + 4(x^(1/3+2))

= x^(5/6) + 4(x^(7/3))

x^(1/3) is y such that y^3 = x

(x^(1/3) × x^(1/3) × x^(1/3)) = x^(1/3+1/3+1/3) = x^1 = x

x^(1/2) = √2 = y such that y^2 = x

(2x)^2 = 4x^2
