Step-by-step explanation:
always begin any problem by writing what you know
circumference is
u = 2 pi r
1)
u=3.14
r=?
3.14 = 2 pi r

Answer:
Father's age = 64 years
Step-by-step explanation:
Given:
Mummy's age = Aliyah's age + 32
Father's age = Mummy's age + 8
Tota age = 144
Find:
Father's age
Computation:
Assume;
Aliyah's age = a
So,
Mummy's age = a + 32
Father's age = a + 32 + 8
Father's age = a + 40
Aliyah's age + Mummy's age + Father's age = Total age
a + a + 32 + a + 40 = 144
3a + 72 = 144
3a = 144 - 72
3a = 72
a = 24
Father's age = a + 40
Father's age = 24 + 40
Father's age = 64 years

Answer:
231q^3
Step-by-step explanation:
Just add them together. They have the same expressions. Whenever you see a number with an ending similarly to another such as 3x and 2x, they can add together.
This is no different. If something is 6x^2 and another is 7x^2, you would add them to get 13x^2.
