Factorise polynomial<br> 27y3 + 125z3<br><br>​
tresset_1 [31]

Answer:

27y^{3} +125z^{3} =(3y)^{3} +(5z)^{3}

Apply the formula for sum of cubes: a^{3}+b^{3}=(a+b)(a^{2}-ab+b^{2})

Therefore:

\left(3y\right)^3+\left(5z\right)^3=\left(3y+5z\right)\left(3^2y^2-3\cdot \:5yz+5^2z^2\right)

=\left(3y+5z\right)\left(9y^2-15yz+25z^2\right)

If b is inversely proportional to c, and b is 5 when c is 12, find b when c = 20.
frozen [14]

Answer:

b=3

Step-by-step explanation:

If b is inversely proportional to c then

b=\frac{k}{c}

b is 5 when c is 12, means...

5=\frac{k}{12}

From where we obtain the value of k, the constant needed, which is equals to 5*12=60

Now... to find b when c=20, is just a matter of using our known variables.

b=\frac{60}{20}=3

Please help me with algebra!<br> Don't answer if you don't know how to do it.
astra-53 [7]
This is all a bit complicated so try and stick with me on this one!

This one is the first problem in the first picture! a + 2 / a^2 + a - 1 / a + 1/ -a^2 - 2a - 1

= a^4 + a^3 - a^2 -  a / -a^5 - 3a^4 - 3a^3 - a^2

= -a^3 - a^2 + a + 1 / a^4 + 3a^3 + 3a^2 + a

= -a^3 - a^2 + a + 1/ a^4 + 3a^3 + 3a^2 + a

= (-a - 1) (a + 1) (a - 1) / a(a+ 1) (a + 1) (a + 1)

= -a + 1 / a^2 + a


The second problem in the first picture! 3x / y + 3x - y^2 / 3xy - 9x^2 + y^2 + 9x^2 / y^2 - 9x^2

= -81x^4y + 18x^2y^3 - y^5 / 243x^5 - 54x^3y^2 + 3xy^4


This one is for the last picture! 4y^2 + 4y + 1 / 4y - 8y^2 - 4y^2 + 1 / 4y + y 

= 16y^3 + 24y^2 / -32y^3 + 16u^2

= 16y + 24 / -32y + 16

= 2y + 3 / -4y + 2

I hope this was helpful!!!

Please remember to rate/thank/mark as brainliest if you see fit! (:
