$f(x) = - 5 {x}^{2} - 4x + 19 \\ plug \: x = - 3 \\ f( - 3) = - 5 {( - 3)}^{2} - 4( - 3) + 19 \\ f( - 3) = - 5 \times 9 + 12 + 19 \\ f( - 3) = - 45 + 31 \\ f( - 3) = -14$

What is 5a(-3b)(2a^2b^3) simplified?

Anna007 [38]

Simplifying $5a(-3b)(2a^2b^3)$ we get $=-30a^3b^4$

Step-by-step explanation:

We need to simplify $5a(-3b)(2a^2b^3)$

Basically, we need to find the product of all terms.

Finding product:

Using exponent rule: $a^b(a^c)=a^{b+c}$

$5a(-3b)(2a^2b^3)$

$=-15ab(2a^2b^3)$

$=-30a^3b^4$

So, simplifying $5a(-3b)(2a^2b^3)$ we get $=-30a^3b^4$
