Answer:
Step-by-step explanation:
product: -18x4 + 15x2 - 15x
the simplification just ends up being the original equation.
 
        
             
        
        
        
M∠BDC=half the arc it faces=1/2 of 54=27
BD is the diameter, so m∠C=90
m∠DBC=180-90-27=63
        
             
        
        
        
What you need to do is multiply both sides by the same number. If 8 times 6 is 48, then 7 times 6 is your answer.
        
             
        
        
        
Answer:
a15 = 50
t25 = 33554427
Step-by-step explanation:
<em>Insert/Substitute the number given in for n.</em>
a15 = 3(15) + 5
a15 = 45 + 5
a15 = 50
~
t25 = 2^25 - 5     <em>2 times itself 25 times. 25 is the exponent in this equation</em>
t25 = 33554432 - 5
t25 = 33554427
