D) 12x^3 - 4x^2 Factorise fully

Mathematics

Vinvika [58]3 years ago

Answer:

The answer for the equation is 4x^2 (3x - 1).

Step-by-step explanation:

Solve:

12^3 - 4x^2

-Factor out the 4 :

12^3 - 4x^2

4(3x^3 - x^2)

-Factor out the x^2 :

4(3x^3 - x^2)

x^2 (3x - 1)

-Then, you rewrite the complete factored expression:

x^2 (3x - 1)

4x^2 (3x - 1)

So, the answer is 4x^2(3x - 1).

What is the approximate age of a woman whose normal systolic pressure measures 125 mm Hg?
sashaice [31]

The approximate age of a woman whose normal systolic pressure measures 125 mm Hg is 31

The function is given as:

P(A) = 0.006A^2 - 0.02A + 120

When the normal systolic pressure is 125, it means that:

P(A) = 125

So, we have:

125 = 0.006A^2 - 0.02A + 120

Subtract 125 from both sides of the equation

0= 0.006A^2 - 0.02A + 120 -125

0= 0.006A^2 - 0.02A - 5

Rewrite the equation as:

0.006A^2 - 0.02A - 5 = 0

Using a graphing calculator, we have:

A = \{30.58, -27.25\}

But age cannot be negative.

So, we have:

A = 30.58

Approximate

A =31

Hence, the age of the woman is 31
