Step-by-step explanation:
30=-5(6n+6)
30=-5×6n-5×6
30=-30n-30
30+30=-30n
60=-30n
60/-30=-30n/30
-2=n

Answer:
B same form
Step-by-step explanation:
By using them for fractions or decimals. You can compare fractions by having them from least to greatest and it helps in getting the same denominator for fractions.
<span>-2x^2-x+7=0
Variable with the highest degree's (exponent) constant, -2 is a, next variable's constant, -1 is b, the constant or number without a variable, 7 is c
using substitution put the numbers into the formula
</span>(-b±√(b^(2)-4ac))/(a^(2))
(-(-1)±√((-1)^(2)-4(-2)(7))/((-2)^(2)) simplify
(1±√(1+56))/4
1±√(57)/4 is your answer
5x + 50 +x
= 5x*2( square ) + 50
