Answer:
x =(10-√112)/2=5-2√ 7 = -0.292
x =(10+√112)/2=5+2√ 7 = 10.292
Consider the converses:
a) If two planes have no points in common, then they are parallel. (true)
b) If a point lies on the y-axis, then it has x-coordinate 0. (true)
c) If two angles have the same measure, then they are congruent. (true)
d) If a figure has four sides, then it is a square. (FALSE) (A figure with 4 sides may not even be a plane figure.)
Answer:
36
Step-by-step explanation: if they do 12 acres per day.. it would be 36 for three days. 12x3=36
Exponential laws
x^-m=1/(x^m)
and (x^m)(x^n)=x^(m+n)
so
(3^-4)(3^2)=
3^(-4+2)=
3^-2=
1/(3^2)=
1/9
the answer is A
