Question

Panjang diagonal suatu persegi (5p-7) cm dan (3p+13) cm tentukan
A. Nilai P
B. Panjang diagonal

Answer 1

Panjang diagonal 1 = panjang diagonal 2

5p - 7 = 3p + 13
5p - 3p = 13 + 7
2p = 20
p = 20/2
p = 10

panjang diagonal = 5p - 7
= 5(10) - 7
= 50 - 7
= 43 cm

Answer 2

5p-7 = 3p+13
2p = 20
a, p= 10
b. 5p-7 = 50-7= 43
   3p+13= 30+13= 43
