Answer:
12, 8, and 4
Step-by-step explanation:
a + d + a + a - d = 24
3a = 24 ⇒ [ a = 8 ]
and (a + d)² + a² + (a - d)² = 224
3a² + 2d² = 224
2d² = 224 - 192 = 32
d² = 16
[ d = ±4 ]
∴ The first three terms to A.P are
a + d = 8 + 4 = 12
a - = 8
a - d = 8 - 4 = 4
∴ Three terms are 12 , 8, and 4
Answer: x=4
Step-by-step explanation: write down 11x-2+9x+1=19x+3, then combine the like terms... 20x-1=19x+3, then subtract 19x from both sides which will give you x-1=3, and 4-1=3 so x=4
