A for ana's age
s for ana's sister's age
a =s4-8
now let's plug in the numbers.
a=(5)4-8
a=20-8
a=12
i'm not completely positive if this is how it should be formatted, but here you go anyways!
Answer:
The factored form is equivalent to the given equation is (x - 2) (x - 3) (x + 4).
Step-by-step explanation:
Since 2 is a zero of the equation
Therefore, (x - 2) is a factor of the equation
Now, on dividing by (x - 2) we get,
as shown in Fig(1)
On factorising x² + x - 12
= x² + x - 12
= x² + 4x - 3x - 12
= x (x + 4) - 3 (x + 4)
= (x - 3) (x + 4)
Now, =
So the factored form is equivalent to the given equation is (x - 2) (x - 3) (x + 4). Therefore option (c) is the correct answer.

Answer:
Average rate of change of the function will be = (-1.5)
Step-by-step explanation:
Average rate of change of a function f(x) is determined by the formula,
Average rate of change = If a < x < b
We have to find the average rate of change of a function g(t) between the interval [-3, 1]
From the given table,
For t = -3,
g(-3) = 6
For t = 1,
g(1) = 0
Therefore, average rate of change of the function in the given interval
=
=
=
= - 1.5
