dade verdadeira.
a) 6×8×12 = 4×12×∆
b) 12×6×15 = 18×4×∆
c) 24×12×23 = 16×18×∆
d) 45×14×38 = 35×18×∆
OBS: ∆ =o número que deve descobrir, me ajudem pfv​

Answer 1

Resposta:

a) 6×8×12 = 4×12×12

b) 12×6×15 = 18×4×15

c) 24×12×23 = 16×18×∆

d) 45×14×38 = 35×18×

Explicação passo-a-passo:

a) 6×8×12 = 4×12×∆

$6*8*12 =4*12* Delta\\Delta = \frac{6*8*12}{4*12}\\Delta = 12\\6*8*12 =4*12*12\\575 = 576$

b) 12×6×15 = 18×4×∆

$12*6*15 =18*4* Delta\\Delta = \frac{12*6*15}{18*4}\\Delta = 15\\12*6*15 =18*4*15\\1080 = 1080$

c) 24×12×23 = 16×18×∆

$24*12*23 =16*18* Delta\\Delta = \frac{24*12*23}{16*18}\\Delta = 23\\24*12*23 =16*18*23\\6624 = 6624$

d) 45×14×38 = 35×18×∆

$45*14*38 =35*18* Delta\\Delta = \frac{45*14*38}{35*18}\\Delta = 38\\45*14*38 =35*18*38\\23940 = 23940$
