what is the question that u need help with

I dont understand what you mean 

a plane inclined at an angle to the horizontal

what is it?

Bored but good

OK.....and you????

1  3/10  is equal to   33/10

33/10 x 4 = 132/10 = 13 2/10 =  13 1/5  =  13.2

Group and add together like terms

(2a^2 + 4a^2) + 12a +1

6a^2 + 12a + 1  

6a ( a + 2)  + 1      

  That is all you can do with this expression UNLESS there is something on the other side of the ' = ' sign

its easier if you just go 9(7+8)  so 7 x 9 = 63 and 8 x 9 = 72 so 63 + 72 = 135 :)

70.6 or 70 5/8 

Using the law of exponents that   a^m * aⁿ = a^{m + n}

5³ * 5²   = 5^{3 + 2}  =  5⁵   =  3125

NOOOOOO HES IN A QUIZ THATS CHEATING!!! :OOOO OML UR HELPING HIM CHEATT OMMGGGG

Assume that there is some integer n , such that  3n + 5 = 364

3n + 5 = 364    subtract 5 from both sides

3n =  359    

To be divisible by 3, the sum of a number's digits must be divisible by 3......but    3 + 5 + 9 =  17......and 17 isn't divisible by 3, so 359 isn't divisible by 3

Therefore....since our conclusion isn't possible, neither is our assumption....and 364 is not in the sequence of 3n + 5

-30/5 = -6

No its not, silly ^-^

y=3(x-7)^2+4

In the form   y = a(x -h)^2 + k, the vetex lies at (h, k)....so....the vertex  = (7, 4)

It's 49 ^-^

Is it negitive 5?

Use foil.

(10*8) + (10*4x)

80+40x

Because these do not have alike terms, 80+40x is the simplest form.

I hope this helps

40,448 x 1 = 40,448
