Question

multiply. (-3x - 0.5) cdot 6.9x =

Explanation:

Step1: Apply distributive property

$(-3x - 0.5)\cdot6.9x=(-3x)\cdot6.9x+(- 0.5)\cdot6.9x$

Step2: Multiply coefficients and variables

$(-3x)\cdot6.9x=-3\times6.9\times x\times x=-20.7x^{2}$ and $(-0.5)\cdot6.9x=-0.5\times6.9x=-3.45x$

Step3: Combine results

$-20.7x^{2}-3.45x$

Answer:

$-20.7x^{2}-3.45x$
