Answer:
- base: 2.18 m
- height: 7.35 m
Step-by-step explanation:
Let b represent the base of the triangle in meters. Then the height is ...
   h = 3 +2b
and the area is ...
   A = 1/2bh
   8 = 1/2(b)(3 +2b)
   16 = 3b +2b^2 . . . . . . . multiply by 2 and eliminate parentheses
   2(b^2 +3/2b + (9/16)) = 16 + 9/8 . . . . . . complete the square
   2(b +3/4)^2 = 17.125
   (b +3/4)^2 = 8.5625 . . . . . divide by 2
   b + 0.75 = √8.5625 ≈ 2.9262
   b = -0.75 +2.9262 = 2.1762
   h = 3 +2b = 7.3523
The base is about 2.18 meters and the height is about 7.35 meters.

Answer:
   x = 5
Step-by-step explanation:
Maybe you have ...
   n(x) = 2x +7
and you want x for n(x) = 17.
   17 = 2x +7
   10 = 2x . . . . . . subtract 7
   5 = x . . . . . . . . divide by 2
