4
Step-by-step explanation:
81 = 3^4
apply the log rule
The answer is A
You’re welcome.
Answer:
Enter the equations.
Multiply each equation by a number to get the lowest common multiple for one of the variables.
Add or subtract the two equations to eliminate that variable .
Substitute that variable into one of the equations and solve for the other variable.
The first is C. r = 4(4/9)
the second one is B. h = 130
the second one is A. k = 7
i’m so sorry, they’re all wrong
Answer:
60degrees
Step-by-step explanation
To get the angle x, you must first know that the sum of angle at a point is 360degrees. Hence;
x + <ADB + <CDB = 360
x +150 + 150 = 360
x+ 300 = 360
x = 360 - 300
x = 60
Hence the value of x is 60degrees
