Answer:
1.-6
Step-by-step explanation:
I don't know how to do the second one but
BD = DC
x+8 = 3x+2
2x=-4
x=-2
-6+12
-6
1/27
1/27
125
Step-by-step explanation:
Given that,
a - b = 3
9^(1/2b) /3^a = 3^(2/2b) /3^a
= 3^b/3^a
= 3^(b-a)
= 3^(-3)
= 27^(-1)
= 1/27
27^(1/3b) /9^(1/2a) = 3^(3/3b) /3^(2/2a)
= 3^b/3^a
= 3^(b-a)
= 3^(-3)
= 27^(-1)
= 1/27
125^(1/3a) /25^(1/2b) = 5^(3/3a) /5^(2/2b)
= 5^a/5^b
= 5^(a- b)
= 5^3
= 125
Answer:
31 and -31
Step-by-step explanation:
Answer:
your answer is y =-8 hopes this help
Angles can be used to estimate the side lengths of a shape.
The letters in order of greatest to least are (a), (b) and (c)
The sum of angles at side (a) is:


The sum of angles at side (c) is:


The sum of angles at side (b) is:


So, we have:



The smaller the base angles, the longer the side.
Hence, the letters in order of greatest to least are (a), (b) and (c)
