(y² - 3)(y⁴ - 6y² + 9)

y²(y⁴ - 6y² + 9) - 3(y⁴ - 6y² + 9)

y².y⁴ - y².6y² + y².9 -3.y⁴ - 3.(-6y²) -3.( 9)

y⁶ - 6y⁴ + 9y² - 3y⁴ + 18y² -27

y⁶ - 6y⁴- 3y⁴ + 9y² + 18y² - 27

y⁶ - 9y⁴ + 27y² - 27

Jamie has a half-sheet cake. If she has six friends, how much will each one get?
sesenic [268]

Answer:

<h2>The answer is </h2><h2>B. 1/12</h2>

Step-by-step explanation:

step one:

From the problem state, we can actually conclude that Jamie wants to share the half sheet of cake among her 6 friends

step two:

we can express this problem mathematically as

=\frac{1}{\frac{2}{6} }

we can inverse the denominator and use a multiplication sign instead

\\\\= \frac{1}{2}*\frac{1}{6}

multiplying both denominators we have

\\\\= \frac{1}{12}

The answer is B 1/12

The sum of the measures of the angles is 180. The sum of the measures of the second and third angles is two times the measure of
grigory [225]
<h2>60,47,73</h2>

Step-by-step explanation:

Let the first angle be a degrees

Let the second angle be b degrees

Let the third angle be c degrees

It is given that sum of angles is 180 degrees.

so,a+b+c=180                      ...(i)

It is given that sum of the measures of the second and third angles is two times the measure of the first angle.

b+c=2\times a                     ...(ii)

It is given that the third angle is 26 more than the second.

c=26+b                                ...(iii)

using (ii) and (iii),

b+b+26=2a

b+13=a

using (i),(ii) and (iii),

a+b+c=a+a-13+26+b=a+a-13+26+a-13=3a

3a=180

a=60

b=a-13=60-13=47

c=26+b=26+47=73
