What is the way to factor a3 plus 27?
3a + 27 = 01. First you subtract 27 from both sides to isolate 3a, the variable.3a = -272. Divide both sides by 3 to get a by itselfa = -9The final answer is a = -9
What is the answer to negative 6x plus 9 equals 9-3x?
the answer is -3x = 0
If 5xequals 9plus 2x then x equals?
If 5 x equals 9 plus 2x then x equals?
For x plus y plus z equals 9 2x-y-z equals -6 and x plus y-z equals 1 what is the echelon matrix?
3x + 2 = 82
Simplify the algebraic expression 7x squared minus 4y plus 3x squared plus 5y plus 2 and evaluate it for x equals 3 and y equals 9?
7(3y-2)-(-4y+9)
What is the value of a in 13a - 6 plus a equals 5a plus 3 plus 3a?
13a - 6 + a = 5a + 3 + 3a 13a + a - 5a - 3a = 3 + 6 6a = 9 6a/6 = 9/6 a = 3/2
What is the answer to 11a plus 9 minus 3A equals -7?
11a-3a =8a so 8a+9=-7 8a = -16 a=-2
What is 3a sqared plus 9?
3a squared plus nine = 19a. 3a to the second power = 9a plus 9 = 19a.
Does the a in both what expressions 3a - 9 equals 6 and 5a plus 2 equals 27 have the same value?
Yes.
X2-14X plus 9 equals?
The given expression does not have rational factors, so the question cannot be abut factorising. Evaluating x2 - 14x + 9 depends on the value of x.
What is a in5a-3a equals 18?
a = 9
4a plus 3-a equals 12?
4a+3-a =12 4a-a = 12-3 3a = 9 a = 3
What is 3a - 6 when a equals 3?
(3 x 3) - 6 = 3 3a-6=3 3a=3+6 3a=9 a=9/3 a=3
A plus 3a plus 5a equals 180?
Gathering like terms together, this can be rewritten: 9a = 180 Dividing both sides of the equation by 9: a = 20
What does A plus 3A plus 9 plus A plus 86 equal?
5a+95 :D
9-3a equals 8 What is a?
9 - 3a = 8Add 3a to each side:9 = 8 + 3aSubtract 8 from each side:1 = 3aDivide each side by 3:1/3 = a
How do you prove that a2 - 6a plus 9 is a perfect square?
a2 - 6a + 9 = a2 - 3a - 3a + 9 = a(a - 3) - 3(a - 3) = (a - 3)*(a - 3) = (a - 3)2
