2/3 - 1/3 would equal 1/3. Since it is a negative 1/3 you would subtract that from the equation.
Answer:

Step-by-step explanation:
As with multiplying any rational expressions, the numerator of the result is the product of the numerators, and the denominator of the result is the product of the denominators.

_____
The denominator product is found using the distributive property. Each of the terms of one factor is multiplied by the other factor.

Answer:
Step-by-step explanation:
Triangle ABC is an equilateral triangle, then:
=> angle ABC = angle BAC = angle ACB = 60 deg
AB // CE, according to alternative interior pair of angles theorem:
=> angle ACE = angle BAC = angle ABC = 60 deg (1)
B, C, and D are colinear, then:
angle ECD + angle ACE + angle ACB = 180 deg
=> angle ECD = 180 - angle ACE - angle ACB = 180 - 60 - 60 = 60 deg (2)
From (1) and (2):
=>angle ACE = angle ECD = 60 deg
Answer:
it is sixty six inches
Step-by-step explanation:
double the radius
Answer:
Step-by-step explanation:
%change=100(final-initial)/(initial)
final=20-12=8 and initial=20 so
%change=100(8-20)/20
%change=100(-12)/20
%change=-1200/20
%change= -60%
