I is -8x^2.
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
We know that when you submit questions you aren't free to use the right format to make the mathematical terms crystal clear. It is likely that you mean "x squared times 6 plus x squared times 2", which is clearer. You can factor out the "x squared" and you will see that you get "x squared times 8". You COULD mean (6x) squared plus (2x) squared, which would be different. 6x times 6x would equal x squared times 36, so your answer will be much different.
(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.
64
x2 + 8x2 = 9x2
3 squared = 97 squared = 49Therefore, the sum is 9 x 49 x 8.This is equal to 3528.
6 squared is 6 x 6 = 36, and 8 squared is 8 x 8 = 64. Multiplying these two results together gives us 36 x 64 = 2304. Therefore, 6 squared times 8 squared is equal to 2304.
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
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

8 squared = 8 x 8 = 64
No they can't. Two 8 times 8 recipes will cover 128 unit squared of space and one 9 times 13 pan will only cover 117 unit squared of space.
