2a + 2s = 32, 6a + 7s = 106
Solve for a in the first equation.
2a = 32 - 2s
a = 16 - s
Substitute a into the second equation.
6(16 - s) + 7s = 106
96 - 6s + 7s = 106
96 + s = 106
s = 10
Substitute s into the first equation.
2a + 2(10) = 32
2a + 20 = 32
2a = 12
a = 6
a = 6, s = 10
The answer would be 18 you subtract 6 and get six then times three

Step-by-step explanation:
Answer:
a) 2x² + 14x + 24 = 0
Step-by-step explanation:
a)
2x² + 14x + 24 = 0
2(x + 4) (x + 3) = 0
x = -4 or x = -3
b)
x² - 6x + 5 = 0
(x - 1)(x - 5) = 0
x = 1 or x = 5
c)
3x² + 30x + 48 = 0
3 (x + 8) (x + 2) = 0
x = -8 or x = -2
d)
-3x² - 12x + 15 = 0
-3 (x + 5) (x - 1) = 0
x = -5 or x = 1
