Answer: 15
<u>Step-by-step explanation:</u>
a₁ = ___, a₂ = 7, a₃ = ____, a₄ = 1575
a₁(r) = a₂
a₂(r) = a₃
a₃(r) = a₄
To get from a₂ to a₄, you have to multiply by r²
⇒ 7r² = 1575
⇒ r² = 225
⇒ r = 15
Answer:
x - y = 3(x + 2)
- x - y = 3x + 6 is the simplified answer and is also correct
Step-by-step explanation:
The difference of x and y is the same as 3 times the sum of x and 2
x - y = 3(x + 2)
x - y = 3x + 6
