Is the expression 30 + x-x2 in standard form?

Mathematics

Answer:

if x2 is x squared, then yes.

Step-by-step explanation:

the two x are not like terms so they cannot be subtracted. Since the 30 does not have an x at the end, it is also not a like term. This expression is simplified and in standard form.

It is but it needs to be rearranged to x^2-2x+30

Number 10:
 All angles in a triangle =180 degrees

so add the first to and subtract that by 180

166 degrees
180-166=14
so x=14 degrees

The amount of oil used by a ship traveling at a uniform speed varies jointly with the distance and the square of the speed. the
muminat
A = kdv^2    where A = amount oil d = distance and v = speed and k is a constant
so 
30 = k*85*42^2
Now solve for k:-
k = 30 / (85*42^2) =     0.00020008

So when d = 26 and v = 54

Amount of oil A = 0.00020008 * 26*54^2
                          =  15.2 barrels

A box with a square base and open top must have a volume of 237276 cm^3. We wish to find the dimensions of the box that minimize
svp [43]

Answer:

A(x)=\dfrac{x^3+949104}{x}

Step-by-step explanation:

Given a box with a square base and an open top which must have a volume of 237276 cubic centimetre. We want to find a formula for the surface area of the box in terms of only x, the length of one side of the square base.

Let the side length of the base =x

Let the height of the box =h

Since the box has a square base

Volume,

V=x^2h=237276\\\\h=\dfrac{237276}{x^2}

Surface Area of the box = Base Area + Area of 4 sides

Area, A(x,h)=x^2+4xh

Substitute h derived above into A(x,h)

Area=x^2+4x(\frac{237276}{x^2})\\\\A(x)=x^2+\dfrac{949104}{x}\\\\A(x)=\dfrac{x^3+949104}{x}

Therefore, a formula for the surface area of the box in terms of only x, the length of one side of the square base is:

A(x)=\dfrac{x^3+949104}{x}
