lcm(9a, 15a²) = 45a² Factorising: 9a = 3² × a 15a² = 3 × 5 × a² lcm = 3² × 5 × a² = 45a²
9a-99 = -90
The two numbers that multiplied together make 324 are 27 and 12. Another way to achieve a result of 324 is to multiply 18 times 18, or by multiplying 54 times 6.
9a - 8a = a
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
9a-99 = -90
It is the same as: 9a -4a = 5a
It is: 9a-a-a = 7a
(a - 6)(2a + 3)
The two numbers that multiplied together make 324 are 27 and 12. Another way to achieve a result of 324 is to multiply 18 times 18, or by multiplying 54 times 6.
9a - 8a = a
If: 9a = 18b Then: a = 2b
