If you mean: -4a+5-2a-9 = 44 then 'a' works out as -8
Check: -(4*-8)+5-(2*-8)-9 = 44
-4a+5-2a-9=44
2a + 9 = 4a - 19 9 + 19 = 4a - 2a 28 = 2a a = 14
2a*3 = 8+4a 6a = 8+4a 6a-4a = 8 2a = 8 a = 4
4a
The GCF is 2a.
x2=(4a)(a) x=√4a2 x=2a The geometric mean of a and 4a is 2a
That factors to (2a - 7)(2a + 9)
4a² - b² = (2a + b)(2a - b)
2a+(-11b)
2a+2a-7b+7b =4a
The expression is: (4a+b)/(2a-5b)
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.
