Solve 2x plus 8 equals 6?
2x+8 = 6 2x = 6-8 2x = -2 x = -1
X-8 equals 2x 19?
x-8=2x*19 x-8=38x x=38x+8 (-37)x=8 x=-8/37≈-0.2162162162162
Does x times x equal 2x?
No, x + x equals 2x. x times x equals x2. (x times x equals x squared.)
What is 2x times 3?
2x times 3 is 6x because 2 multiplied by 3 is 6.2x times 3x would be 6x to the power 2 because 2x3=6 and x times x = xsquared
How do you find the perimeter of 2x and 3x?
(2x x 3x) x 2 = 12x (2x times 3x times 2)
What is 2x x 4x x x?
2x times 4x is 8x squared- then that times x is 8x to the power of three.Mathmatically represented as 8x^3
Is there a solution to 20 equal 2x minus 8 times 6?
2x - (8 x 6) = 20 2x = 20 + 48 2x = 68 x = 68/2 x = 34
What is (2x to the eighth power)(-4x)(3x to the second power)?
2x^8 x 3x^2 x -4x = -24x^11
When 8 is subtracted from two times a number the result is 10 what is the number?
8-(2x)=10 -(2x)=10-8 -(2x)=2 x=2/(-2) x= -1
When the expression x power by 2 plus 2x-8 is factoredthe two roots will equal?
If: x^2 +2x -8 then it is (x-2)(x+4) when factored
4 times the sum of a number and 5 is 8 more than twice the number?
4(x + 5) = 2x + 8 4x + 20 = 2x + 8 2x = -12 x = -6
What is 2x to the negative one third power times 2x to the third power minus x to the one third power?
2X -1/3 * 2X3 - X 1/3 Order of operation; multiply first. ( multiply coefficients, add exponents ) 4X 8/3 - X 1/3 3X 7/3 =====
How do you factor x to the power 3 plus 8?
x^3 + 8 = (x + 2)(x^2 - 2x + 4)
Why is 2x cubed different from 2x times 2x times 2x?
2X * 2X * 2X = 8X^3 2X^3 is saying 2*( X * X * X) = 2X^3
What is -7 plus 2x equals x plus 8?
-7 +2x = x + 8 2x - x = 7 + 8 x = 15
2x-3 equals x plus 5?
2x-3 = x+5 2x-x = 8 x = 8
Are 2 to the power of x and 2x the same?
No. 2x means 2 times x. For example, 210 = 1024, while 2 x 10 = 20.
