Answer:

Step-by-step explanation:
Distribute 2 through the parentheses.
5x+3=-8x-10+2x
Collect like terms
5x+3=-6x-10
Move variable to the left-hand side and change its sign. Move constant to the right-hand side and change its sign.
5x+6x=-10-3
Collect like terms. Calculate the difference
11x=-13
Divide both sides by 11 and you get
x= -13/11

Answer:
-5xa^2-7a^3+7a^2+4
Step-by-step explanation:
Answer:
2.4 hours
Step-by-step explanation:
David's time = 6 hours
Anthony's time = 4 hours
the combined time is given by the following formula
1/ (david's time) + 1/(anthony's time) = 1/total time
1/6 + 1/4 = 1/Total
4/24 + 6/24 = 1/Total
10/24 = 1/ total (taking reciprocal of both sides)
24/10 = total
total time = 24/10 = 2.4 hours
Ok, so it seems
erm
ok, even and odd
it is an odd one because the power is odd (3rd degree)
so then the ends go in different directions
and since leading coefient (5 in the 5x^3) is positive, it goes from bottom left to top right
so
A is false
B is false
C and D are true
answer is C and D
