Answer:
Step-by-step explanation:
1)
2(x – 4) + 32
Multiply it out.
2 * x - 2 * 4 + 32
2x - 8 + 32
2x + 24
2)
9x + 4(x + 2) – 5
Multiply it out
9x + 4 * x + 4 * 2 - 5
9x + 4x + 8 - 5
13x + 3
You're adding .4 each time.
Answer:
96
Step-by-step explanation:
commom difference = d
a₆ + a₇ = 16
a₅ + a₈ = (a₆ - d) + (a₇ + d) = a₆ + a₇ = 16
a₄ + a₉ = (a₆ - 2d) + (a₇ + 2d) = a₆ + a₇ = 16
Similarly,
a₃ + a₁₀ = 16, a₂ + a₁₁ = 16, a₁ + a₁₂ = 16
so
a₁ + a₂ + ... + a₁₁ + a₁₂ = 6 x 16 = 96
