Answer:
1 solution
Step-by-step explanation:
8m = - 48 ( divide both sides by 8 )
m = - 6 ← is the only solution
Answer:
Step-by-step explanation:
By the Pythagorean theorem, triangle BCD has
and triangle ABD has
.
Substituting the first equation into the second equation for 
gives the equation
Now triangle ABC has
Expanding out the left side, 
.
Now substitute the equation from before, 
, into the new equation.
We work to isolate 
by adding 
to both sides of equation and subtracting 
from both sides.
Divide both sides by 2 and you get 
Assume that x is positive and square root both sides to get the final result of
Answer A
Step-by-step explanation: 2+2=22-55= -12-5= -7 then take away the negative then look outside and u should see a tree. Your final answer should be s=1/7t
