6. A quadrilateral has one line of symmetry only. Select all conclusions that must be true. n All sides of the quadrilateral have the same length.
All angles of the quadrilateral have the same measure.
✓ Two sides of the quadrilateral have the same length.
✓ Two angles of the quadrilateral have the same measure.
No sides of the quadrilateral have the same length.
No angles of the quadrilateral have the same measure.

the discriminant is 64 + 4*1*12 = 112

this is prime.

step-by-step explanation:

unless if u could do my questions, if not i wouldn't want to

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752

answer: group b.
