lcm(9a, 15a²) = 45a² Factorising: 9a = 3² × a 15a² = 3 × 5 × a² lcm = 3² × 5 × a² = 45a²
9a-99 = -90
9a - 8a = a
The two numbers that multiply to give 324 are 18 and 18. This is because 18 multiplied by 18 equals 324. In mathematical terms, this can be represented as 18 x 18 = 324. Therefore, the numbers 18 and 18 are the factors of 324.
9a squared = 81a^2
lcm(9a, 15a²) = 45a² Factorising: 9a = 3² × a 15a² = 3 × 5 × a² lcm = 3² × 5 × a² = 45a²
-a^2- 9a - 18 = 0 -(a^2 + 9a + 18) = 0 -(a + 6)(a + 3) = 0
8/9a
a= -4
so 5a = -20 making a = -4
(a - 6)(2a + 3)
9a-99 = -90
It is the same as: 9a -4a = 5a
It is: 9a-a-a = 7a
9a - 8a = a
If: 9a = 18b Then: a = 2b
The two numbers that multiply to give 324 are 18 and 18. This is because 18 multiplied by 18 equals 324. In mathematical terms, this can be represented as 18 x 18 = 324. Therefore, the numbers 18 and 18 are the factors of 324.
