Answer:

$x=\begin{bmatrix}-2\\-1\\\end{bmatrix}$

Step-by-step explanation:

(x+2) (x+1)=0

Isolate the X

=> $\left(x+2\right)\left(x+1\right)=0$

Divide both sides by the coefficient:

=> $x=\begin{bmatrix}-2\\-1\\\end{bmatrix}$

By applying Cathetus theorem, the value of x is equal to 10 units.

<h3>How to determine the value of x?</h3>

In order to determine the value of x, we would apply Cathetus theorem (leg rule), which states that each leg of a right-angled triangle is the geometric mean that's directly proportional between the hypotenuse and the part of the hypotenuse that's directly below the leg.

In this context, we have:

x² = m × a

x² = (21 + 4) × 4

x² = 25 × 4

x² = 100

x = √100

x = 10 units.
