Answer:

red area = 7.74 in^2

Step-by-step explanation:

area of square = 6x6 = 36

radius = 1/2 diameter, radius = 3

area of circle = (3.14)(3^2) = 28.26

36-28.26 = 7.74

PLEASE HELP!
RUDIKE [14]

3x^2 + 23x - 8 can be factored into (3x - 1)(x + 8). To double-check, you can multiply the terms together again using FOIL: first, outside, inside, last.


(3x)(x) + (3x)(8) + (-1)(x) + (-1)(8)


3x² + 24x - x - 8


3x² + 23x - 8


Check.

Sasha can mow 3/8 of an acre of grass in 45minutes.how many acres of grass does Sasha now per hour?
horrorfan [7]
Keeping in mind that an hour is 60 minutes.

\bf \begin{array}{ccll}
\stackrel{acre}{grass}&\stackrel{minutes}{time}\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
\frac{3}{8}&45\\
g&60
\end{array}\implies \cfrac{\frac{3}{8}}{g}=\cfrac{45}{60}\implies \cfrac{\frac{3}{8}}{\frac{g}{1}}=\cfrac{45}{60}\implies \cfrac{3}{8}\cdot \cfrac{1}{g}=\cfrac{45}{60}
\\\\\\
\cfrac{3}{8g}=\cfrac{45}{60}\implies 180=360g\implies \cfrac{180}{360}=g\implies \cfrac{1}{2}=g
