Solution: (3x + 4y - 3z) x (3x + 4y + 3z)
Answer:
2, 10, 50, 250
Step-by-step explanation:
Using the formula with a₁ = 2 , then
a₂ = 5a₁ = 5 × 2 = 10
a₃ = 5a₂ = 5 × 10 = 50
a₄ = 5a₃ = 5 × 50 = 250
The first 4 terms are 2, 10, 50, 250
c = 2 × 14.6 × π = 29.2 × 3.141592 = 91.7344864 ≈ 91.7
Correct anawer: B
Answer: It is a 25% increase.
Step-by-step explanation: First lets subtract her new wage from her old wage. 10 - 8 = 2
Next, lets write an percent equation, for p = percent.
2 = p x 8
Basically, we are saying that her new wage will be what percent of her old wage.
Next,
2/8 = p
0.25 = p
Now, multiply 0.25 by 100 to get a percent
0.25 x 100 = 25
So her new wage is a 25% increase from her old wage.
