Answer:
Step-by-step explanation:
If we let x represent one of the numbers, then you want ...
x(58 -x) = 201.25
x² -58x +201.25 = 0 . . . . . put in standard form
(x² -58x +29²) +201.25 -29² = 0 . . . . complete the square
(x -29)² -639.75 = 0
x -29 = ±√639.75 . . . . . add 639.75 and take the square root
x = 29 ±√639.75 . . . . . . add 29
The two numbers of interest are ...
29 +√639.75 ≈ 54.2933
29 -√639.75 ≈ 3.7067

Answer:
1. -19x
3. 23 - 8x
5. -18x + 2y
Step-by-step explanation:
first: 3x - x = 2x
2x - 22x = -20x
-20x + x = -19x
second one:
8 - (-15) = 23
12x - 20x = -8 x
23 - 8x
third:
-10x - 8x = -18x
3y - y = 2y
-18x + 2y
