If by decomposition you mean breaking it ino parts then
break it itno 2 triangles and 1 rectangle
left to right
triangle with base y and height h
h=10
y=3
area of traignel=1/2bh
aera=1/2(10)(3)
area=5(3)
area=15
rectangel of legnth x and height h
area=legnth timwe width
x=8
h=10
area=8 times 10
aera=80
last triangle
should be same as other sinces same base (y) and same height (h)
15
add
15+80+15=120
Ok, I think this is the answer. 70% chance that it is Not a white shirt.
2.)
0 = 6x + 3y +9
-3y = 6x + 3y - 3y +9

By isolating y we now have the equation in slope intercept form:

Where m = slope and b = y- intercept. Therefore, the slope is -2 and the y - intercept is -3.
4.)
Similarly, #4 is already in slope intercept form so we can solve it by inspection. So for #4 the slope is -1 and the y - intercept is 2.
Each side is 9 cm. a square has equal sides, so 36 divided by 4= 9
Answer:
It’s not the answer but it’s a guide and something to be mindful of...
Step-by-step explanation:
You have to determine the zeros of the rational inequality by setting each factor equal to zero then solving for x. Use the zeros as critical numbers to divide the number line into distinct intervals.
Hope this helps... bless your heart.
