Answer 1

Jawaban:

lim 5(x² + 2x) = ....

x → 3

Maka:

lim 5(x² + 2x)

= 5(3² + 2(3))

= 5((3×3) + (2×3))

= 5(9 + 6)

= 5(15)

= 5 × 15

= 75

Kesimpulan:

nilai dari lim 5(x² + 2x) = 75

Answer 2

Penyelesaian :

Lim 5(x² + 2x)

x→3

Jawab :

• Lim 5(x² + 2x)

x→3

• 5(3² + 2(3))

• = 5((3 + 3 + 3 ) + 2(3))

• = 5(( 6 + 3 ) + 2(3))

• = 5( 9 + 2(3))

• = 5( 9 + ( 2 + 2 + 2 ))

• = 5( 9 + ( 4 + 2 ))

• = 5( 9 + 6 )

• = 5(15)

• = ( 15 × 5 )

• = 75
