Answer:

Step-by-step explanation:
Assuming the geometric series is

then nth term is
,
and the first term is found when
:

36 cm²s⁻¹ is the rate at which the area of the square is increasing.
Given each side of the square is increasing at a rate of 6cm/s
Area, A = s², s is the side length
=>
{chain rule of differentiation}
= 6 cm/s
When A = 9 cm² => 9 = s²
=> s = √(9) => s = 3 cm
Hence,
= 2 × 3 × 6 = 36 cm²s⁻¹
Hence, 36 cm²s⁻¹ is the rate at which the area of the square increases

Answer: It is
Step-by-step explanation:
3/12 is actually a quarter which is equal to 0.25. It certainly isn't an irrational number, but is indeed a rational one.
3(4x - 3) - 7x = 5x - 9
First, expand your equation so it will be easier to simplify.
Second, multiply (3)(4x) to get 12x.
Third, multiply (3)(-3) to get -9.
Fourth, combine the like terms. (x and -9 alone).
Fifth, subtract (12x + -7x) to get 5x.
Sixth, change 5x + -9 into a subtraction.
Seventh, since both sides are equal, that means that the equation has infinite solutions.
Answer:
B) infinite solutions
