1) Amount of white sugar ÷ the amount of brown sugar =

\frac{2}{3}÷\frac{1}{4}

=\frac{2}{3}.\frac{4}{1}= \frac{8}{3}=2\frac{2}{3}.

2)Amount of white sugar after increase =

\frac{2}{3}+2\frac{1}{2}=\frac{2}{3}+\frac{5}{2}=\frac{19}{6}=3\frac{1}{6}.

3)Amount of flour after increase=2\frac{1}{4}+2\frac{1}{2}=\frac{9}{4}+\frac{5}{2}=\frac{19}{4}=4\frac{3}{4}.

4) Amount of brown sugar =

\frac{1}{4} cup.\frac{1}{4}of\frac{1}{4}=\frac{1}{16}

\frac{1}{16} cup was used .

5)Amount of Baking soda used=

\frac{1}{4}of\frac{1}{16}=\frac{1}{64}

How do you find the area of the field in <br> terms of x
Alex_Xolod [135]

Hello from MrBillDoesMath!


Answer:  104x^2 + 166x + 66

Discussion:

The area of a rectangle is given by "length" * "width". For us the formula becomes

 (13x + 11) * (8x+6)


or

13x (8x +6) + 11 * (8x + 6)  =


(13x * 8x + 13x* 6) + ( 11*8x + 11*6) =

(104x^2 + 78x ) + (88x + 66) =

104x^2 + (78x + 88x) + 66 =


104x^2 + 166x + 66


Thank you,

MrB
