N³- n² + 3n - 3 = (n²+3 )(x-1 )
Answer:
Jack = 48 years old , Lac = 12 years old
Step-by-step explanation:
Jack = 4Lacy
(Jack - 4) + (Lacy - 4) = 52
Now, substitute.
4Lacy - 4 + Lacy - 4 = 52
5Lacy = 60
Lacy = 60/5 = 12
Jack =4Lacy
=4(12)
=48
Answer:

Answer:
Step-by-step explanation:
Ratio = 4 :3
Other two sides = 4x , 3x
Pythagorean theorem
(4x)² + (3x)² = 20²
16x² + 9x² = 400
25x² = 400
x² = 400 ÷ 25
x² = 16
x = √16
x = 4 cm
4x = 4*4 = 16
3x = 3*4 = 12
Sides = 16cm , 12 cm
