Question

Dacă a=8 si b+c=12, calculati: 5+a×b+ac​

Answer 1

Răspuns:

a=8

b+c=12

5+ab+ac=5+a·(b+c)=5+8·12=5+96=101

Answer 2

Răspuns:$\bf \red{\underline{~ 101~}}$

Explicație pas cu pas:

$\bf a = 8$  

$\bf b+c=12$  

$\bf\underline{~ 5+a\cdot b+a\cdot c ~=~ ?~~~}$  

$\bf 5+a\cdot b+a\cdot c = 5+a\cdot( b+ c) =5 + 8\cdot 12 =$

$\bf 5 +96 =\red{\underline{~ 101~}}$
