Answer:

Look below.

Step-by-step explanation:

From looking at this figure we could break it up into 3 different shapes and find the area of each giving us the area of the shape by adding.

Area of a square formula: A=LW

Area of a triangle formula: A=1/2bh

Rectangle:

A=8 x 4

A=32

Triangle 1:

A=1/2bh

A=1/2(3)(2)

A=3

Triangle 2:

A=1/2bh

A=1/2(3)(3)

A=4.5

Now add them all together to get your area of the figure.

32+3+4.5=39.5

Area=39.5

Charles will babysit for up to 4 hours and charges $7 per hour. Write a function in function notation for this situation.

Sloan [31]

X hour and 7 dollars per hour

x = hour

7(x) is your function

thank you for Anlian for pointing it out.. there is 4 hours

so x = 4

plug in 4 in x. 7(4)

7 x 4 = 28

28 is your answer

hope this helps

$\text{Hey there!}$

$\mathsf{-\dfrac{5}{2}a+5=25}$

$\text{\bf{SUBTRACT}}\mathsf{\ by\ 5\ on\ your\ sides}\\\mathsf{-\dfrac{5}{2}a+5-5=25-5}\\\\\mathsf{Cancel\ out: 5-5\ because\ it\ gives\ you\ 0}\\\\\mathsf{Keep: 25 - 5\ because\ it\ helps\ us\ solve\ for\ a}\\\\\mathsf{25-5=20}\\\\\mathsf{New\ equation:- \dfrac{5}{2}a=20}$

$\text{\bf{MULTIPLY}}\mathsf{\ \dfrac{2}{-5}\ on\ your\ sides}\\\\\mathsf{\dfrac{2}{=5}\times\dfrac{-5}{2}a=\dfrac{2}{-5}\times20}\\\\\mathsf{Cancel\ out: \dfrac{2}{-5}\times\dfrac{-5}{2}\ because\ it\ gives\ you\ 1}\\\\\mathsf{Keep: \dfrac{2}{-5}\times20\ because\ it\ gives\ you\ the\ value\ of\ a}\\\\\mathsf{\dfrac{2}{-5}\times20=-8}$
