How do you solve (3x plus 7)2?
To solve ((3x + 7)^2), you can use the formula for squaring a binomial, which is ((a + b)^2 = a^2 + 2ab + b^2). Here, (a = 3x) and (b = 7). Applying the formula gives: [ (3x + 7)^2 = (3x)^2 + 2(3x)(7) + 7^2 = 9x^2 + 42x + 49. ] So, ((3x + 7)^2 = 9x^2 + 42x + 49).
What is the answer to -3x plus 9x?

12x plus 6 equals 9x-15?
-7 (negative 7) transpose the 9x then transpose the 6. divide both sides by 3x and your answer will be -7 =]
What is the answer to 9x squared minus 9x minus 10?
9x2-9x-10 = (3x+2)(3x-5) when factored
How do you factor 9x squared minus 49?
It is a difference of squares. 9x^2-49=(3x+7)(3x-7)
Is y plus 7 equals 3x and 9x-y equals -7 parallel with each other?
No because they don't have the same slope (9x & 3x)
Simplify x plus 5 plus 3x - 7 plus 9x plus 3 - 4x?
x+5+3x-7+9x+3-4x Collect like terms: 9x+1
What is the gcf of 9x and 15x?
3x. 15x - 9x = 6x 9x - 6x = 3x 6x - 3x = 3x 3x - 3x = 0
X plus 5 plus 3x - 7 plus 9x plus 3 - 4x?
x + 5 + 3x - 7 + 9x + 3 - 4x Switch the like numbers closer to make the equation easier. x + 3x + 9x - 4x + 5 - 7 + 3 However this is an unsolvable as it isn't an equation. An equation needs an equals sign, for example: x + 3x + 9x - 4x + 5 - 7 + 3 = 0, or x + 3x + 9x - 4x + 5 - 7 + 3 = 10 If it is the former then the answer is 9x = -1 Thus x = -1/9

What is the answer to 12x plus 6 equals 9x plus 27?
12x + 6=9x + 27 12x-9x + 6=9x - 9x + 27 subtract 9x from both sides. 3x + 6 = 27 simplify 3x + 6 - 6=27 - 6 subtract 6 from both sides. 3x=21 simplify 3x/3=21/3 divide both sides by 3 x=7 simplify 12(7) + 6=>84+6=>90 9(7) + 27=>63+27=>90 It checks out!
