x = 2 so x squared = 4 and 2x squared = 2 times 4 = 8; y = 4 so xy = 2 times 4 = 8 and 3xy = 3 times 8 = 24; y squared = 4 times 4 = 16 and 4y squared = 4 times 16 = 64; so 8 + 24 - 64 = 32 - 64 = -32
Oh, dude, when you add 6x squared and 2x squared, you get 8x squared. It's like combining 6 apples with 2 apples and ending up with 8 apples. So, in math terms, 6x squared plus 2x squared equals 8x squared. Easy peasy!
(x-8)(x+8)
To solve the expression 8x^2 * 2x, you first multiply the coefficients (8 * 2 = 16). Then, you multiply the variables with the same base by adding their exponents (x^2 * x = x^(2+1) = x^3). Therefore, the simplified expression is 16x^3.
It is: -x squared
x2 + 8x2 = 9x2
3 squared = 97 squared = 49Therefore, the sum is 9 x 49 x 8.This is equal to 3528.
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.
Why don't you figure it out yourself
8 x 8 = 64
x = 2 so x squared = 4 and 2x squared = 2 times 4 = 8; y = 4 so xy = 2 times 4 = 8 and 3xy = 3 times 8 = 24; y squared = 4 times 4 = 16 and 4y squared = 4 times 16 = 64; so 8 + 24 - 64 = 32 - 64 = -32
Yes, x times x equals x squared.
Cubed; Area is squared. Short version: No, squared is to the second power, cubed to the third. Long version: No- squared is X2 , or x times x. Cubed is X3, or x times x times x. For example: Squared: 22= 2x2= 4 Cubed: 23= 2x2x2= 8 So any 3-D object has to be X3. Area, which is 2-D, is squared.

16 to the 4th power, or 16 x 16 x 16 x 16 = 65,536
Oh, dude, when you add 6x squared and 2x squared, you get 8x squared. It's like combining 6 apples with 2 apples and ending up with 8 apples. So, in math terms, 6x squared plus 2x squared equals 8x squared. Easy peasy!
8 squared = 8 x 8 = 64
