Question

área de um retangulo de altura 2x-3 e comprimento 2x+3

Answer 1

$\large\boxed{\begin{array}{l}\sf A=c\cdot \ell\\\sf c\longrightarrow comprimento\\\sf \ell \longrightarrow largura\\\sf A=(2x+3)\cdot(2x-3)\\\sf A=(2x)^2-3^2\\\sf A=4x^2-9\end{array}}$

Answer 2

✔OLÁ!!!

A = c . h

A = (2x + 3) . (2x - 3)

A = (2x)² - 3²

A = 4x² - 9
