LnA +LnB= LnA.B
so we get <span>Log3(X-5)+log3(x+3)=Ln3(x-5)(x+3)=2 implies
</span>(x-5)(x+3)=2^3=8, so we can solve easily the quadratic equation
x^2-2x-23=0, there are two solution x=1 -sqrt(24), and x=1+sqrt(24)
C is the answer because its longer and a big number sentence
Answer:
total length: 2 1/6 ft Leftover: 4 5/6 ft How many: 2
Step-by-step explanation:
Total length: add 2/3ft and 1 1/2 ft together.
Leftover: Subtract 2 1/6ft from 6ft
How many: Multiply 2 1/6 by 2
Answer:
118 degrees
Step-by-step explanation:
m = 124 / 2 = 62
Sum of opposite angles m and n is supplementary,
m + n = 180
62 + n = 180
n = 180 - 62
n = 118 degrees
First of all, to simplify expressions we use the PEMDAS
then we do the right needed inverse to move the variables all to one side and the other numbers to another... this is a way we simplify expressions
Hope this helps :)
