It has 1 solution i believe
Completing the square
alrighty
minus 31 both sides
x²+12x=-31
take 1/2 of the linear coefient and square it
12 is the linear coefient
12/2=6, (6)²=36
add that to both sides
x²+12x+36=36-31
factor perfect square trinomial
(x+6)²=5
square root both sides, remember to take positive and negative root
x+6=+/-√5
so what you want to write is
x+6=√5 and
x+6=-√5
the solutions
minus 6 both sides
x=-6+√5 and -6-√5
The answer is 6,5 on the graph
Answer:
8/9
Step-by-step explanation:
the equation is x = k / y
when x = 2 & y = 8 then k is 16
when you is 18 then x = 8/9
longer congruent sides = 6-0 OR 4-(-2) = 6units
perimeter= 3.6×2 + 6×2 = 19.2units
height of parallelogram= 2-(-1) = 3 units
area= 3×6 = 18unit^2
