What is 2a squared x 3a negative cube?
2a2 x 3a-3 = (2 x 3)a(2 + -3) = 6a-1
What is a plus 3a-2 plus 3a simplified?
7a minus 2, if "3a-2" means 3a minus 2. 3a plus 1 and 1-3rd in parenthesis times 3a, if "3a-2" means 3a squared. a plus 3a squared plus 3a = 1-3rd times 3a plus 3a times 3a plus 1 times 3a = 3a plus 1 and 1-3rd in parenthesis times 3a
Which is the smallest no when divided by 12 and 18 leaves the remainder 9?
(1) x/12=a+9, where a is an integer (2) x/18=b+9, where b is an integer 3x(1) + 2x(2) gives 3x/36 + 2x/36 = 5x/36 = 3a+27+2b+18 = 3a+2b+45 5x/36=3a+2b+45 x=36(3a+2b+45)/5 x=36(3a+2b)/5+9 as 36 is not divisible by 5 then 3a+2b should be divisible by 5 then the smallest solution is a=0 and b=0 and x=9
-2(3a plus 2) plus 2?
-2(3a+2)+2=
How do you do this A x 3 a plus 12?
Simplifying a = 3a + 12 Reorder the terms: a = 12 + 3a Solving a = 12 + 3a Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-3a' to each side of the equation. a + -3a = 12 + 3a + -3a Combine like terms: a + -3a = -2a -2a = 12 + 3a + -3a Combine like terms: 3a + -3a = 0 -2a = 12 + 0 -2a = 12 Divide each side by '-2'. a = -6 Simplifying a = -6
What is 3a² 3a²?
3a^2 + 3a^2 = 6a^2 3a^2 - 3a^2 = 0 3a^2 x 3a^2 = 9a^4 3a^2 divided by 3a^2 = 1
What is x3 plus ax plus 3a plus 3x2?
x^3 + ax + 3a + 3x^2 = (x^3 + 3x^2) + (ax + 3a) = x^2(x + 3) + a(x + 3) = (x + 3)(x^2 + a)
What is 2a squared x 3a negative cube?
2a2 x 3a-3 = (2 x 3)a(2 + -3) = 6a-1
What is 3a X 3a X 3a X 3a?
81(a^4)
What is 3a x a?

How do you divide a fraction with a variable by a whole number?
2/3a / 4 = 2/3a / 4/1 = 2/3a x 1/4 = 2/12a = 1/6a
Simplify 5a plus 4b - 3a?
5a + 4b - 3a =(5a - 3a) + 4b =2a + 4b =2 (a + 2b)
Simplify a plus 3a-2 plus 3a?
a + 3a - 2 + 3a. Add the a + 3a + 3a = 7a. You can't combine the -2 & 7a so the solution is: 7a - 2.
What is a plus 3a-2 plus 3a simplified?
7a minus 2, if "3a-2" means 3a minus 2. 3a plus 1 and 1-3rd in parenthesis times 3a, if "3a-2" means 3a squared. a plus 3a squared plus 3a = 1-3rd times 3a plus 3a times 3a plus 1 times 3a = 3a plus 1 and 1-3rd in parenthesis times 3a
What is a x a x a?
3a
What is 3a x 2a plus 5?
= 3 X 2 = 6 = a X a = a2 (a square) = 6a2 + 5 Answer
Find the value of c for which the roots of 2x2-21x c0?
2x^2 - 21x + c = 0 x^2 - 21x/2 + c/2 = 0 (x + a)(x + 2a)= x^2 - 21x/2 + c/2 x^2 + 3a + 2a^2 3a = -21/2 ------> a = -7/2 2a^2 = c/2 ---> 49/2 = c/2 ---> c = 49
