Question2. A rectangle has dimensions $x+10$ $2 \mathrm{x}-3$, where x is in centimetres. Tir area of the rectangle is $54 \mathrm{~cm}^{2}$. b) What is the value of $x$ ? $2 x^{2}-17 x-84=0$

Studdy Solution
Verify the solutions. Since $x$ represents a length, it must be a non-negative value. Thus, $x = -3.5$ is not valid in this context.
The valid solution is $x = 12$.
The value of $x$ is:
$$\boxed{12}$$
