Use orders of operations.
40 -  {2}^{2}  \times 9 + 17 \\ 40 - 4 \times 9 + 17 \\ 40 - 36 + 17 \\ 4 + 17 \\  = 21

A book 500 pages (500 sheets of paper) long is 2.25 inches thick. If each cover is 0.125 inches thick, how thick is each sheet o
luda_lava [24]
Subtract the thickness of the covers from the total thickness of the 500-pages book. Since each cover is 0.125 inches thick, double this value and subtract from 2.25 inches. This results to 2 inches. To determine the thickness of each of the pages, divide 2 inches by 500 pages. Therefore, the thickness of a single page is 4x10^-3 inch.

(Please help) Which answer describes the polynomial?
lbvjy [14]
\bf 3x^3+4x^2-7\quad 
\begin{cases}
3x^3\impliedby &3rd~degree\\
4x^2\impliedby &2nd~degree\\
7\impliedby &0~degree
\end{cases}

notice, there are three terms, therefore is a trinomial.

the term that has the highest degree, has a degree of 3, therefore the degree of the polynomial as a whole is 3, or a cubic degree.

so, is a cubic trinomial.

C<br> Solve for m:<br> 3/4m - 3 = 9<br> May I please have help!
MAVERICK [17]

Answer:

m=16

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :  3/4*m-3-(9)=0

Step 1: Simplify 3/4

Equation at the end of step 1: ((3/4 x m) - 3) - 9 = 0

Step2: Subtracting a whole from a fraction

Rewrite the whole as a fraction using  4  as the denominator :

        3     3 • 4

   3 =  —  =  —————

        1       4  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

3m - (3 • 4)                               3m - 12

—————4———————  =  ———4————

When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 3•(m-16)

 ———————— • 4 = 0 • 4

    4    

Now, on the left hand side, the  4  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  3  •  (m-16)  = 0

6.2      Solve :    3   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solve  :    m-16 = 0

Add  16  to both sides of the equation :

                     m = 16
