Answer:
base = 3x - 1
height = x
area of triangle = (1/2)bh
22 = (1/2)(3x-1)(x)
44 = (3x-1)(x)
44 = 3x^2-x
0 = 3x^2-x-44
0 = 3x^2-12x+11x-44
0 = (3x^2-12x)+(11x-44)
0 = 3x(x-4)+11(x-4)
0 = (x-4)(3x+11)
x = {-11/3, 4}
throw out the negative solution (extraneous) leaving
x = 4 m (height)
.
Base:
3x - 1 = 3(4) - 1 = 12 - 1 = 11

Answer:
6x - 7y?
Step-by-step explanation:
2x3y + 8xy - 4x2y - 16y
10x11y - 4x2y - 16y
6x9y - 16y
6x - 7y
(I'm also confused by this problem, but I tried to provide my viewpoint of how I'd solve it)
(Feel free to ask questions or ask for clarifications)
(1) 2800 - 15% of 2800 =
2800 - 0.15(2800) =
2800 - 420 = 2380
(2) if he is reducing it by 15%, then he is actually eating 85%....
0.85(2800) = 2380
Usually, the covered product will have an indication that it carries either a full warranty or a limited warranty. The federal Magnuson-Moss Warranty Act regulates all consumer product warranties for items costing consumers more than fifteen dollars ($15.00), requiring that they be designated as either full or limited.
