Question

me ajudem nesses cálculos​

Answer 1

Explicação passo-a-passo:

a) y( 5y - 2)= 0 >>>>>> y = 0

5y - 2 = 0

5y = 2

y= 2/5

___________________

b.) x( 7x - 35 ) = 0 >>>>> y= 0

7x - 35 = 0

7x = 35

x= 35/7

x = 5

______________________

c) x( - x - 10 ) = 0 >>>>>> x = 0

x= 10

_______________________

d) x( x +3) = 0 >>>>>>>> x = 0

x = -3

________________________

e) x (- 2x +10 )= 0 >>>>>>> x= 0

-2x = - 10

x = 10/2

x = 5

Espero que esteja tudo certo!
