6a - 8 - 4a - 2 → 6a - 4a - 8 - 2 → 2a - 10
To determine if ( 4(4a - 8) ) is equivalent to ( 6a ) and ( 8a - 8 ), we can simplify both expressions. First, simplify ( 4(4a - 8) ): [ 4(4a - 8) = 16a - 32 ] Now let's compare ( 16a - 32 ) with ( 6a ) and ( 8a - 8 ). Clearly, ( 16a - 32 ) is not equivalent to ( 6a ) or ( 8a - 8 ). Thus, ( 4(4a - 8) ) is not equivalent to either expression.
a3 - 2a2 + 4a - 8 = a2(a - 2) + 4(a - 2) = (a - 2)(a2 + 4)
4a + 2 = Answer let a = 2 then Answer equals 4(2) + 2 = 8 + 2 = 10.
−4a + 139 = 4a + 123 → −8a = −16 → a = 24a + 123 → 4(2) + 123 = 8 + 123 = 131°

to solve this expression: 10a-4(a+2) -> 10a-4(a)-4(2) -> 10a-4a-8 -> 6a-8
a = -2-4a/3-2 = 8-4a = 8(3-2) times both sides by (3-2)-4a = 24-16-4a = 8-a = 2 divide both sides by 4a = -2 times both sides by -1
a3 - 2a2 + 4a - 8 = a2(a - 2) + 4(a - 2) = (a - 2)(a2 + 4)

(a - 2)(a^2 + 4)
To find the value of (4a - 2b) given (a = 2) and (b = 3), we first substitute the values into the expression. Calculating: [ 4a - 2b = 4(2) - 2(3) = 8 - 6 = 2. ] Thus, the value of (4a - 2b) is 2.
-2 + 8 = 6
