Answer:
3(2040x-4039)/4x
Step-by-step explanation:
W=4L/9
A=LW, using W found above gives us
A=L(4L/9)
A=4L^2/9 and we were told that A=576 so
4L^2/9=576 multiply both sides by 9
4L^2=5184 divide both sides by 4
L^2=1296 take the square root of both sides
L=36, and we know that W=4L/9 so
W=4(36/9)=16
So the dimensions are: width=16in and length=36in
The answer is the bottom left one :D
Answer:
11. x = -16
12. k = 6
13. x = -19
14. x = -6
15. x = -20
16. Combining like terms isn't to be used on this type of problem. I'm sorry, can you guess on this one?
17. x = 19
18. n = -10
19. b = 11
20. n = 4
21. r = -6
22. n = -4
Again super sorry about question 16 :(
Answer:
ab - b^2
Step-by-step explanation:
The area of the large rectangle is
A = l*w
=a*b
The area of the unshaded region is
A = b*b = b^2
The area of the shaded region is the area of the rectangle minus the area of the unshaded region
ab - b^2
