Question

60. Jika P = (-3)² - (-5)² dan Q = (-8) × 15 + (-13) × (-8), maka nilai P ÷ Q = ....
A. -2 C. 1
B. -1 D. 2​

Answer 1

Jawaban:

C. 1

Penjelasan dengan langkah-langkah:

Nilai P

P = ( - 3 )² - ( - 5 )²

P = 3² - 5²

P = ( 3 x 3 ) - ( 5 x 5 )

P = 9 - 25

P = - 16

Nilai Q

Q = ( - 8 ) x 15 + ( - 13 ) x ( - 8 )

Q = (( - 8 ) x 15 ) + (( - 13 ) x ( - 8 ))

Q = ( - 120 ) + 104

Q = - 16

Nilai P ÷ Q

- 16 ÷ ( - 16 )
