To simplify this, we need to do PEMDAS (parenthesis then exponents, then multiplication and division, then addition and subtraction). Here, we can't combine any like terms in the parenthesis. Since there's no exponents, that means that the next step is to do multiplication. This gives us:
3 - 15y - 21 + 2y - 6
Now we can combine like terms.
(-15y + 2y) + (3 - 21 - 6)
-13y - 24
Answer:
x=-2,-4 is your answer
x²+6x+8=0
doing middle term factorization
x²+4x+2x+8=0
x(x+4)+2(x+4)=0
(x+4)(x+2)=0
either
x=-4
or
x=-2
Answer:
1) Communism: government led by a single party often authoritarian.
2) Democracy: government that allows people to choose their leaders.
3) Socialism: government that owns goods and services. It encourages cooperation rather than competition.
4) Oligarchy: government of a few individuals usually wealthy, of certain race often authoritative rulers.

6) Theocracy: leader of a specific religion.
7) Totalitarianism: Government of one person without limitations of power.
8) Military Dictatorship: countries ruled by one person with absolute power.
Step-by-step explanation:
4x2=8 then multiply it by 3 to find how much the aquarium can hold which would be 24 of how much water
For the first option, since when x is going down (to the left) the function is going up, it's not approaching 0. For the second option, since when x is going up (to the right) it's going up, it's not approaching negative infinity (negative infinity is all the way down). For the third one, since when x is going down the y values are climbing, we can assume that the function's values go to positive infinity. For the last one, since when x=0 y=0, when x=0 the function does not go to infinity
