Answer:
40x² + 65x + 25

Explanation:
We will just multiply each term from the first bracket by each term from the second and then combine like terms to get the final expression.

This would be done as follows:
(5x + 5)(8x + 5)
5x(8x) + 5x(5) + 5(8x) + 5(5)
40x² + 25x + 40x + 25
40x² + 65x + 25

Hope this helps :)

Answer:

Step-by-step explanation:

Volume of first container = 48 cm³

πr²h = 48 cm³

Second container:

height = (2/3)h

Volume of second container=

=\pi *r^{2}*(\frac{2}{3}*h)\\\\=\frac{2}{3}*\pi *r^{2}*h\\\\

=(2/3)* first container's volume      {πr²h = 48 cm³}

=\frac{2}{3}*48\\\\=2*16\\\\

= 32 cm³

Help please, Which expression does not belong? Explain your reasoning.
ZanzabumX [31]

Answer:

My best answer is option number 4.

Step-by-step explanation:

Because the first 3 answers follow a specific pattern in addition and division, i.e. they only go up to 4 different numbers, whereas with the 4th option, that changes. Not only that, but if you look closely, the 4th option adds 6 to itself 5 times, that's the same as 6x5, which equals 30, so if you divide 30 by 5, its almost pointless seeing as how you already know it's gonna get you 6.
