so 5a = -20 making a = -4
a= -4
The expression "9a plus 1" can be written mathematically as (9a + 1). This represents a linear equation where (a) is a variable. The value of the expression depends on the value of (a). For example, if (a = 2), then (9a + 1) equals (19).
It is: 12a+2 when simplified
Since 2 plus 4 is not 10, the "if" statement is false. Given a false "if", logically, 9 + 2 can equal anything you like.
In order to solve something, there needs to be an equation. If I have read your equation right you have: (a² - 4)/(2 + 6a) x (3 + 9a)/(a² + 5a + 6) This looks like it needs to be simplified. There are two fractions being multiplied, so multiply the numerators and denominators together, giving: (a² - 4)/(2 + 6a) x (3 + 9a)/(a² + 5a + 6) = ((a² - 4)(3 + 9a)) / ((2 + 6a)(a² + 5a + 6)) Now, simplify the polynomials to remove the squared terms and any common factors: a² - 4 = (a - 2)(a + 2) 2 + 6a = 2(1 + 3a) 3 + 9a = 3(1 + 3a) a² + 5a + 6 = (a + 3)(a + 2) Giving: ((a² - 4)(3 + 9a)) / ((2 + 6a)(a² + 5a + 6)) = ((a + 2)(a - 2)3((1 + 3a))/(2(1 + 3a)(a + 3)(a + 2)) This can now be simplified by cancelling out equivalent terms, giving: ((a + 2)(a - 2)3(1 + 3a))/(2(1 + 3a)(a + 3)(a + 2)) = ((a - 2)3) / (2(a+3)) = 3(a - 2) / 2(a + 3) = (3a - 6) / (2a + 6)
a= -4
The expression "9a plus 1" can be written mathematically as (9a + 1). This represents a linear equation where (a) is a variable. The value of the expression depends on the value of (a). For example, if (a = 2), then (9a + 1) equals (19).
9a + 4a = 26 13a = 26 a = 26/13 a = 2
(9a + 2)(9a + 2)
2 + 3A + 9A = 2 + 12AThe numerical value depends on the value of 'A'.It changes whenever 'A' changes.
-a^2- 9a - 18 = 0 -(a^2 + 9a + 18) = 0 -(a + 6)(a + 3) = 0
It is: 12a+2 when simplified
a(a^2 - 9a + 3)
9a^2 + 42at + 49t^2 = (3a + 7t)(3a + 7t)
You use Plus as a symbol in Maths. Example, 2 Plus 2 equals 4. Or in symbols it would be 2+2=4. __________________________ Plus = + Equals = = (Equals equals =)
no if 1 plus 1 equals 2 then 2 plus 2 equals 4.
No.
