Question

QUIZZZ !!!

x+y = 24
x-y = 4

maka x²-y² = ....?​

Answer 1

Verified answer

Jawaban:

96

Penjelasan dengan langkah-langkah:

x + y = 24

x - y = 4

..

x - y = 4

x = 4 + y

..

x + y = 24

4 + y + y = 24

2y = 20

y = 10

..

x = 4 + y

x = 14

..

x² - y²

= 14² - 10²

= 196 - 100

= 96

Answer 2

x + y = 24

x - y = 4

x - y = 4 (pindah ruas)

x = 4 - (-y)

x = 4 + y

x + y = 24 (input nilai x)

(4 + y) + y = 24

4 + (1 + 1)y = 24

4 + 2y = 24

y = 24 - 4/2

y = 20/2

y = 10/1

y = 10

x = 4 + 10

= 14

MAKA :

14² - 10²

= (14(14) - (10(10)

= 196 - 100

= 96

NILAI X² - Y² = 96
