Answer:

B

Step-by-step explanation:

3 x -9 which is -27. Then you have to add the exponents, so it will be x^4+2 = x^6 , y^3+2 = y^5, z^1+2 = z^3. so your answer will be -27 x^6 y^5 z^3

What would the answer to this question be? show work please
AURORKA [14]

Answer:

B

Step-by-step explanation:

The volume of a rectangular prism is the length times width times height.

V = LWH

V = (4√3)(3√6)W

V = 12√18 W

V = 36√2 W

If the volume is irrational, then W cannot have a radical that is half of a perfect square, because when multiplied by √2, that would yield a rational volume.  For example, √18 × √2 = √36 = 6.

Therefore, the answer must be B, because 12 is not half of a perfect square.

V = 36√2 (4√12)

V = 144√24

V = 288√6

Which sequence represents an arithmetic sequence?
Sergio039 [100]

we know that

arithematic sequence will always have common difference

(a)

−5, −7, −10, −14, −19, …

we can see that

d_1=-7+5=-2

d_2=-10+7=-3

they are not equal

so, this is not arithematic sequence

(2)

1.5, −1.5, 1.5, −1.5, …

we can see that

d_1=-1.5-1.5=-3

d_2=1.5+1.5=3

they are not equal

so, this is not arithematic sequence

(3)

4.1, 5.1, 6.2, 7.2, …

we can see that

d_1=5.1-4.1=1

d_2=6.2+5.1=1.1

they are not equal

so, this is not arithematic sequence

(4)

−1.5, −1, −0.5, 0, …

we can see that

d_1=-1+1.5=0.5

d_2=-0.5+1=0.5

they are equal

so, this is arithematic sequence

Help! Clear the fractions
I am Lyosha [343]

Answer:

x = - \frac{27}{20}

Step-by-step explanation:

Given

\frac{5}{6} x + 2 = \frac{7}{8}

Multiply through by 24 ( the LCM of 6 and 8 ) to clear the fractions

20x + 48 = 21 ( subtract 48 from both sides )

20x = - 27 ( divide both sides by 20 )

x = - \frac{27}{20}
