Step-by-step explanation:
<u>Let the numbers be x, y and z</u>
- x + y + z = 24
- 2y = z + 2
- z = x + y
<u>Solving by substitution:</u>
- x + y + z = z + z = 24
- 2z = 24
- z = 12
- 2y = z + 2
- 2y = 12 + 2
- 2y = 14
- y = 7
- z = x + y
- x = z - y
- x = 12 - 7 = 5
<u>The answer:</u>
7x - (25x^2 + 12x) = 7x - 25x^2 - 12x = -25x^2 - 5x

Explanation:
−((10)(2)−(2)(8)+(5)(−1))
= −(20−(2)(8)+(5)(−1))
= −(20−16+(5)(−1))
= −(4+(5)(−1))
= −(4+−5)
= −(−1)
= 1
