lcm(9a, 15a²) = 45a²
Factorising:
9a = 3² × a
15a² = 3 × 5 × a²
lcm = 3² × 5 × a² = 45a²
9A
That is at least a 1975 tractor. What model is it?
It is the same as: 9a -4a = 5a
It is: 9a-a-a = 7a
9a-99 = -90
The expression (9a - a - a) simplifies to (9a - 2a), which equals (7a). So, the final result is (7a).
9a - 8a = a
If: 9a = 18b Then: a = 2b
9a verbal expression
9a squared = 81a^2
The expression "9a plus 1" can be written mathematically as (9a + 1). This represents a linear equation where (a) is a variable. The value of the expression depends on the value of (a). For example, if (a = 2), then (9a + 1) equals (19).
