24 because 12 + 12 = 24 and and CD = DB
CB = CD + CB = 24 the triange ADC and ADB are equal
Answer:
Look below
Step-by-step explanation:
Let's start by converting 4 m into cm:


Since Megan's chain is only 400 cm long, Mason's chain is longer by 79 cm.
Answer:
Distribute, then combine like terms, subtract 10 from both sides of the equation, simplify, divide both sides of the equation by the same term, and simplify to get your solution.
Step-by-step explanation:
1.) Distribute
6−2(4−5)=40
6−8+10=40
2.) Combine like terms
6a-8a+10=40
-2a+10=40
3.) Subtract 10 from both sides of the equation
-2a+10=40
-2a+10-10=40-10
4.) Simplify
subtract the numbers
-2a+10-10=40-10
-2a=40-10
subtract the numbers
-2a=40-10
-2a=30
-2a=30
5.) Divide both sides of the equation by the same term
-2a=30

6.) Simplify
cancel terms that are in both the numerator or denominator

a=
Divide the numbers
a=
a=-15
a=-15
7.) Solution
a=-15
Answer:
C: perpendicular lines
