Four times a number x equals 4x.
x = number Four times the number (4x) is the same as the number increased by 78 (x + 78). Since they are both equal, then 4x = x + 78 4x - x = 78 3x = 78 x = 26
She isn't. 4x squared is 4 times (x squared). That is, 4 times (3 squared) = 4 times 9. If you want it to be the square of 4x (which would be the square of 4 times 3, ie, 12), you have to write it as (4x)squared.
4x
Let's represent the # with x 4x-8=8(x+2) 4x-8=8x+16 4x-8x=16+8 -4x=24 x=24/-4 x=-6 The number is -6
4x^4 or 4x*4x*4x*4x A formula would be (x^a)(x^b)= x^a+b x^a) / (x^b)= x^a-b
2x times 4x is 8x squared- then that times x is 8x to the power of three.Mathmatically represented as 8x^3
Four times a number x equals 4x.
Well, darling, 4 times x squared is simply 4x^2. It's as easy as pie, no need to complicate things. Just plug in your x value and do the math, honey.
4x - 6 = 22 Therefore, 4x = 28 x = 28/4 x = 7
3 |4x-10| = 18 |4x-10|=6 4x-10 = 6 4x-10=-6 4x=16 4x=4 x=4 x=1
4x
(x + 4) (x - 4) = x2 - 16To work this out you need to multiply each term in the first bracket by each term in the second bracket.So you would do x times x which gives you x2.Then x times -4 which is -4x.Then 4 times x which 4x. (Note: this 4x will cancel out the -4x)And finally 4 times -4 which is -16.So you end up with x2 - 4x + 4x - 16 which equals x2 - 16.
x = number Four times the number (4x) is the same as the number increased by 78 (x + 78). Since they are both equal, then 4x = x + 78 4x - x = 78 3x = 78 x = 26
A lack of spacing between symbols indicates multiplication. In this case, "4x" is another way of saying "4 times x", or "x + x + x + x". 'x' is an unknown variable. For example, if you were to say: 4x = 8 That's a way of saying "four times a certain value is equal to eight". The solution in this case is that x equals two, as four times two is equal to eight. You can see this by dividing both sides of the equation by four: 4x = 8 4x / 4 = 8 / 4 x = 2
