Answer 1

Jawaban:

Penyelesaian :

Dik :

• X = 4

• Y = 10

Dit :

• x² + 7x - y × x = ?

Jawab :

• x² + 7x - y × x

• = 4² + 7(4) - 10 × 4

• = ( 4 + 4 + 4 + 4 ) + 7(4) - 10 × 4

• = ( 8 + 4 + 4 ) + 7(4) - 10 × 4

• = ( 8 + 8 ) + 7(4) - 10 × 4

• = 16 + 7(4) - 0 × 4

• = 16 + ( 7 × 4 ) - 10 × 4

• = 16 + 28 - 10 × 4

• = 16 + 28 - ( 10 × 4 )

• = 16 + 28 - 40

• = ( 16 + 28 ) - 40

• = 44 - 40

• = 4

Answer 2

x = 4

y = 10

nilai dari x² + 7x - y × x

= x² + 7x - y × x

= 4² + 7(4) - 10 × 4

= 16 + 28 - 40

= 44 - 40
