68/4 + 25/2
_
f(x) = 7(x) + 2(x)
f(3) = ..​

Penjelasan dengan langkah-langkah:

~ No 1

[tex] \sf \frac{68}{4} + \frac{25}{2} = \frac{68}{4} + \frac{25 \times 2}{2 \times 2} [/tex]

[tex] \sf \frac{68}{4} + \frac{50}{4} = \frac{68 + 50}{4} [/tex]

[tex] \sf \frac{118 \div 2}{4 \div 2} = \frac{59}{2} [/tex]

[tex] \bf = 29 \frac{1}{2} [/tex]

------

~ No 2

f(x) = 7(x) + 2(x)

f(3) = 7(3) + 2(3)

f(3) = (7 × 3) + (2 × 3)

f(3) = 21 + (2 × 3)

f(3) = 21 + 6

f(3) = 27

Jawaban:

68/4 + 25/2

34/2 + 25/2

(34+25)/2

59/2

= 29 1/2

f(x) = 7(x) + 2(x)

f(3) = ..

penyelesaian :

f(3) = 7(3) + 2(3)

f(3) = 21 + 6

f(3) = 27
