Answer: 9.6 units
<u>Step-by-step explanation:</u>
The formula for the length of a diagonal (d) for a rectangular prism given length (L), width (w), and height (h) is: d² = L² + w² + h²
Given: L = 8, w = 2, h = 5
d² = 8² + 2² + 5²
d² = 64 + 4 + 25
d² = 93
√d² = √93
d = 9.6
I'm pretty sure its xy, x, -3y and 2
First, write 8x^3 in exponential form (8 is basically the same as 2^3)
So that you have 2^3*x^3+1
Multiply the terms with equal exponents by multiply the bases (1 is basically the same as 1^3)
So that it becomes (2x)^3+1^3
Then, using a^3+b^3 equals (a+b)(a^2-2ab+b^2), factor the expression so that it becomes
(2x+1)((2x)^2-2x+1^2)
Expand the second bracket
So the two factors are (2x+1) and (4x^2-2x+1)
