${12x}^{3} + {2x}^{2} - 30x - 5 \\ = 2 {x}^{2} (6x + 1) - 5(6x + 1) \\ = (6x + 1)( {2x}^{2} - 5)$

Hope this helps. - M

In △XYZ , XZ=9 , YZ=4 , and XY=7 .

Mamont248 [21]

Answer:

$A=6\sqrt{5}\ units^2$

Step-by-step explanation:

we know that

Heron's Formula is a method for calculating the area of a triangle when you know the lengths of all three sides.

so

$A=\sqrt{s(s-a)(s-b)(s-c)}$

where

a, b and c are the length sides of triangle

s is the semi-perimeter of triangle

we have

$a=9\ units,b=4\ units,c=7\ units$

Find the semi-perimeter s

$s=\frac{9+4+7}{2}=10\ units$

Find the area of triangle

$A=\sqrt{10(10-9)(10-4)(10-7)}$

$A=\sqrt{10(1)(6)(3)}$

$A=\sqrt{180}\ units^2$

Simplify

$A=6\sqrt{5}\ units^2$
