Answer:

The Volume is 660^3.

1. Match the polynomial identity to the correct answer.

Katen [24]

Answer:

$a: (a-b)(a+b);b: (a-b)(a^{2}+ab+b^{2}); c: (a^{2} +2ab+b^{2}); d: (a+b)(a^{2}- ab+b^{2})$

Step-by-step explanation:

Given the expressions all that is required is to expand them (using the distributive property) to see which answers they match up to:

For a: $(a-b)(a+b)=a^{2} +ab-ab-b^{2} =a^{2}-b^2$

For b: $(a-b)(a^2+ab+b^2)=a^3+a^2b+ab^2-a^2b-ab^2-b^3=a^3-b^3$

For c calculate the square of a sum: $(a+b)^2=a^2+ab+ab+b^2$

(add like terms) c: $a^2+2ab+b^2$

For d: $(a+b)(a^2-ab+b^2)=a^3-a^2b+ab^2+a^2b-ab^2+b^3$ $=a^3+b^3$

Your gym membership costs $33 per month after an initial membership fee . you paid a total of $228 after 6 months.

Lubov Fominskaja [6]

So, what I did was multiply 33*6 and got 198 and then 228-198 to find out that the initial fee was 30 dollars. then multiply 33*9+30 to get a 9 month total cost of $327. Hope from here you are able to set up your equation now you have all the information needed :)

Geometry Question Please Help!!!!

lora16 [44]

The equation of a parabola is given by $f(x)=a(x-h)^{2}+k$ where $(h,k)$ is the vertex.

We have the vertex is (-3,-2) so we have $h=-3$ and $k=-2$

Substituting -3 and -2 into the $f(x)$
$f(x)=a(x--3)^{2}+(-2)$
$f(x)=a(x+3)^{2}-2$

Hence, the correct answer is option D

Step-by-step explanation:

There is a rule between operations. I mean that you have to follow these stpes:

Parentheses

Exponents

Multiplication

Division

Addition

Subtraction

You can remember as "Please Excuse My Dear Aunt Sally" or PEMDAS.

In this question: 5x5+2.8÷2.2+3.3= 25+16÷4+3=25+4+9=38
