2a^3=8+4a2a^3-4a-8=0 a^3-2a-4=0 It occurred to me just now by looking at the equation that a=2 would work. And it does. So that's your answer.
Not sure why it is 3a2- if you mean 3*a*2, then: 3*a*2=6a (6a-2a)+5-2(a (or a2)+a)=1 4a+5-(2a+a)=1 4a+5-2a-a=1 Then take the 5 over (remember, the +5 become -5 when transposed): 4a-2a-a=1-5 Solving the equations on both sides gives: a=-4 Is this your answer?
That factors to (2a - 7)(2a + 9)
2a/3=8+4a2a=3(8+4a) 2a=24+12a -10a=24 a=-24/10 a=-12/5
the value that makes this ewuation true 5a=a is 2a
Solve the following equation for A : 2A/3 = 8 + 4A
Solve the following equation for A : 2A/3 = 8 + 4A
When you multiply 2a by 2a, you are essentially multiplying 2 by 2 and a by a separately. This results in 4a^2, where the coefficient 4 is the product of 2 and 2, and a^2 represents a multiplied by a. Therefore, the final answer is 4a^2.
The value of a is -7
2a + 9 = 4a - 19 9 + 19 = 4a - 2a 28 = 2a a = 14
depends what the value of 'a' is.
2a*3 = 8+4a 6a = 8+4a 6a-4a = 8 2a = 8 a = 4
The GCF is 2a.
4a
x2=(4a)(a) x=√4a2 x=2a The geometric mean of a and 4a is 2a
