The expression "8x plus 5x" simplifies to ( (8 + 5)x ), which is ( 13x ). The reference to "when x8" seems unclear, but if you meant "when x = 8," then substituting gives ( 13(8) = 104 ). Thus, the expression evaluates to 104 when ( x = 8 ).
If x = 8 and y = 10 then it is 44.
No.

2x8(x8) = (2)(x8)(x8) = 2(x8+8) = 2(x16) = 2x16

I'll assume you mean x6 + x8 + x3 Note if this is what you want to ask, then the best way to type it where you have no formatting capabilities would be:x^6 + x^8 + x^3 (the carat '^' symbol means 'raise to the power of')So the highest power of x is 8.

X -8 same as, 1/X8 ====
8 x 0.25 = 2
