12x^2 - 4x + 15x - 5

-4 * 15 = 12 * -5

Factor out greatest common factor

4x(3x - 1) + 5x(3x - 1)

Factor polynomial

(3x - 1)(4x + 5)

Answer:

Step-by-step explanation:

Hi so basically you just convert the inches to decimals so

0.5 x 0.5 x 0.25 = 0.0625

Use a calculator to convert 0.0625 into fraction which is $\frac{1}{16}$

Multiply $\frac{1}{4}$ by 3 = $\frac{1}{64}$

Then multiply $\frac{1}{16}$ by $\frac{1}{64}$ = 4

Soo that was probably very confusing, but I hope it helps! :)

Plz click the Thanks button, I rrly appreciate it!
