Question

A²+4a para a=2/5

Mandem a conta pra mim pfvr

É pra hj!!!

Answer 1

${a}^{2} + 4a$

$a = \frac{2}{5}$

$( \frac{2}{5} ) {}^{2} + 4 \times \frac{2}{5} =$

$( \frac{2}{5} \times \frac{2}{5} ) + \frac{8}{5} =$

$\frac{4}{25} + \frac{8}{5} =$

25,5 | 5

5 , 1 | 5

1 , 1 MMC 5×5 = 25

$\frac{4 + 40}{25} =$

$\frac{44}{25} = 1.76$
