I mean I honestly do not know
7x^2 + 11x - 6
--------------------------
7x^2 - 10x + 3
(7x - 3)(x + 2)
= -----------------------
(7x - 3)(x - 1)
x + 2
= --------------
x - 1
answer is
<span>
quantity x plus 2 over quantity x minus 1</span>
As we know that one million is 1,000,000.
So we can write it as:-
➢ 1×10⁶
Answer:
Step-by-step explanation:
<u>Time needed if they work together:</u>
- 1 / (1/11 + 1/9) =
- 1/ (20 / 99) =
- 99/20 ≈ 5 hours
Dr/dt= 8cmM-¹
dA/dt = ?
but A= πr²
so dA/dr =2πr
but recall
dA/dt = dA/dr • dr/dt
dA/dt = 2πr • 8cmM-¹
dA/dt = 2×π×39 ×8 = 624cm²M-1
