B.7y+6
Add 3y and 4y together since it’s both y
Answer:
yes becasue their sides have the same length and angles
Step-by-step explanation:
Most of these problems are the commutative property:
Addition
a + b = b + a
Multiplication
a * b = b * a
and the associative property:
Addition
(a + b) + c = a + (b + c)
Multiplication
(a * b) * c = a * (b * c)
There's also the Identity property:
Addition \ Subtraction:
a + 0 = a \ a - 0 = a
Multiplication \ Division:
a * 1 = a \ a / 1 = a
Using the rules of logarithms, you can change it to
ln() + ln() =
ln(27)
This is because when you have a factor in front of a logarithm, that turns into an exponent, and when you add logarithms, you multiply the factors inside of the logarithm.
So your final answer is
D.
