Melody i need to ask Andre something , thats about adding something to the website!how can i do so?

If the problem is written as  cos(60)(47),  then you would find the  cos(60)  and multiply it by  47;

however, I can't remember when I saw a problem written like that.

Hi!! my name is bella. I am student in Central High School.

Density is mass divided by volume.

You will need to know the volume; then, divide the mass by the volume.

Is the problem  1 - (2 - a)² - (2 - a)(2 + a) - 4a ?

If so

use FOIL on   (2 - a)²  =  (2 - a)(2 - a)  =  4 -2a - 2a + a²  =  4 - 4a + a²

use FOIL on  (2 - a)(2 + a)  =  4 + 2a -2a - a²  =  4 - a²

Substitute:

1 - [( 2 - a)² ] - [ (2 - a)(2 + a) ] - 4a

1 - [ 4 - 4a + a² ] - [ 4 - a² ] - 4a

Distribute the minus signs:

1 - 4 + 4a - a² - 4 + a² - 4a

Combine like terms:

=  -7

So we shall solve this as

13 = (4x + 2)

(now at first we will open the brackets of 4x + 2 )

13 = 4x +2 

(now we will take 2 to the other side with 13 and also change it from 2 to -2 as when we change places even signs change)

-2 + 13 = 4x

(and now we will simply subtract -2 and 13 )

11 = 4x

(now we will take 4 to the other side and then divide it by 11)

x = 11/4

x= 2.75  ANSWER

i hope you have understood by now but if not then pls be free to ask!

hope this helps you!

To find the slope and the y-intercept from an equation for a straight line, place the equation in slope-intercept form:  y  =  mx + b;  that is, solve the equation for y.

The coefficient of x will be the slope, the number added or subtracted at the end will be the y-intercept.

-3x + 4y  =  -8

Add 3x to both sides:

         4y  =  3x - 8

Divide by 4:

           y  =  (3/4)x - 2

The slope is  3/4 ; the v-intercept is  -2.

big thanks =) =)

The unit circle has a radius of one and is centered at the origin; therefore, every value for x must be in the range  -1 ≤ x ≤ 1  and every value for y must also be in the range  -1 ≤ y ≤ 1.

3√3 is outside the unit circle.

Obviously, if you are instructed to use one, use that one.

The ancient roots of measurement of the earth (geometry) and the sky (astronomy) was based upon degrees; so, if you are in geometry class or measuring a direction, such as 22° east of north, use degrees.

Radians are normal to our base 10 number system; degrees aren't. Once you are in calculus, radians occur naturally; degrees don't.

1−(2−a)(2)−(2−a)(2+a)−4a

Distribute:

=1+2a+−4+a^2+−4+−4a

Combine Like Terms:

=1+2a+−4+a^2+−4+−4a

=(a^2)+(2a+−4a)+(1+−4+−4)

=a2+−2a+−7

Answer: =a2−2a−7

Triangle is a polygon with three sides.

For example:

So thats a triangle with three sides!

No!  9 + 10 = 19

you stupid

thanks!!!

i dont know what exactly do you mean but 60 as a fraction i think would be 60/1 that indicates a whole 60

g(-2)=-3(-2)+4=6+4=10

g(4)=-3(4)+4=-12+4=-8

Therefor g(4) is smaller than g(-2).

the answer is g(75)

I believe that given the equation two divided by three x with negative twenty and negative six doing my math i believe the answer is 24

2+2 = 4 

the anser iss 7

what you do is hold shift and press 6 and it will come up like ^ and in a problem it should look like 8^2
