Answer:
-x^8y^2 -2y^7 -2xy^4 -6xy
Step-by-step explanation:
Eliminate parentheses.
xy^4 + 5y^7 - 6xy - 7y^7 - x^8y^2 -3xy^4
Arrange in descending degree order, group like terms.
-x^8y^2 +(5y^7 -7y^7) +(xy^4 -3xy^4) -6xy
Combine like terms.
Answer:8^4 + 14^36 is the perimeter because they are for sides in a rectangle so you have to double the amount.
19+19= x
So x, is 38. Just add 19 and 19
the solution for x²+2x+8<0
-5x +3(2x) = 2
-5x +6x = 2
x=2
