Depending on what shape or figure you are talking about, generally volume= Bh B= area of the base and for area greatly depend on what the object is.
square= side cubed 
rectangle= L time H
triangle= base time height divided by 2
circle= pi time radius cubed 
that should get you through what you need.

Prism; Surface area = Lateral Area + 2(base) 
            Volume = Base times height
Cylinder; surface area = lateral area + 2(base) 
               Volume = Base times height
Pyramid; Surface area = Lateral times base
                Volume = 1/3 base times height
Cone; Surface area= Lateral area + base 
           Volume= 1/3 base times height

Question 4(Multiple Choice Worth 1 points) (07.04 LC) Factor completely 49x2 − 9. (7x + 3)(7x − 3) (7x + 3)(x − 3) (7x − 3)(7x −
scoundrel [369]

Answer:

A

Step-by-step explanation:

We take a look at this expression: 49x^2-9 and notice that both terms are square numbers. 49x^2=(7x)^2 and 9=3^2.

There is a specific formula that I highly recommend you memorize involving differences of squares. It states that given the difference of squares a^2-b^2, it can always be factored into (a+b)(a-b).

Here, we can apply that. In this case, a = 7x and b = 3. So:

49x^2-9=(7x)^2-3^2=(7x+3)(7x-3)

Thus, the answer is A.

Hope this helps!

Serggg [28]

Answer:

There is 7/15 left in the bag

Step-by-step explanation:

So, you need to find a common denominator between 3 and 5 which is 15

multiply the numerator and the denominator by 3 in 1/5. Then, multiply the numerator and the denominator by 5 in 1/3.

1/3*5=5/15

1/5*3=3/15

Add them together.

5/15+3/15=8/15

Lastly, subtract 15/15 by 8/15

15/15-8/15=7/15
