Question

Înlocuieste literele cu factori numerici:
a×a=9
b×b=16
c×a=25
a×b=12
bxc=20
a×c=15
b×c-a×c=5
a×c+b×c=35
c×c-a×b=13

Answer 1

a × a = 9
3 × 3 =9

b × b = 16
4 ×4 =16

c × a = 25
( aici nu are sens, pt ca a=3 si 25 nu se imparte exact la 3)

a×b =12
3×4=12

b×c =20
4×5 = 20

a×c = 15
3 × 5 =15

b×c - a×c =5
4 ×5 - 3×5 = 5
20 - 15 =5

a×c + b×c =35
3×5 + 4 ×5 =35
15 + 20 =35

c×c - a×b =13
5 × 5 - 3 ×4 =13
25 - 12 =13
