Tolong no 101 sampai no 104 Plissss pakai cara Difoto aja cara nya

101) L = p × l
L = ( y + 5 ) ( y - 2 )
L = y² + 5y - 2y - 10
L = y² + 3y - 10 ( A )

102) misal
lebar = x
panjang = x + 3
K = 2 × ( p + l )
K = 2 × ( x + 3 + x )
K = 2 × ( 2x + 3)
K = 4x + 6 ( D )

103) misal
panjang = 3y
lebar = 2y
K = 2 × ( p + l )
K = 2 × ( 3y + 2y)
K = 2 × 5y
K = 10y ( A )

104) h(t) = 30t - t²
h(3) = 30(3) - (3)² = 90 - 9 = 81 m ( C )
