The area is 40in.
all you need to do is multiply all the numbers together.
8x5=40 so you area is 40in
(f*g)(x) = (x-4)(2x+1) = 2x² + x - 8x - 4 = 2x² - 7x - 4
(f-g)(x) = x-4 - (2x+1) = (x-4)-2x-1 = -x - 5
(f+g)(3) = 3 - 4 + 2*3 + 1 = -1 + 6 + 1 = 6
The slope is 15/30

Answer:
x=11, y=1 or (11, 1)
Step-by-step explanation:
I used substitution to solve this. Basically wherever there's an x, I would fill it in as 12-y.
2(12-y)+3y=29
24+2y+3y=29
24+5y=29
subtract 24 from both sides
5y=5
divide by 5
y=1
Now substitute y back in to get x.
x=12-1
x=11
You can also graph this into desmos, and wherever they intercept, that's your answer. I hope this helps!
