Question

scoateti factorul comun in afara parantezelor , apoi calculati. 4×35+4×52+4×13. 9×15+15×6+5×15. 12×91-12×44‐12×17. 113×58-15×113-133×43​

Answer 1

Explicație pas cu pas:

1. 4x 35 + 4x 52 + 4x 13 = 4×(35+52 + 13) = 4 ×100= 400

2. 9x15+ 15 ×6+ 5x 15 = 15 x ( 9+ 6+6) =

15 x 21 = 36

3. 12 x 91 - 12x44 - 12 x 17 =

12 x( 91 - 44 - 17) = 12 x 30 = 360

4. 113 x 58 - 15 x 113 - 113 x 43 =

113 x ( 58- 15 - 43) = 113 x0 = 0
