To get $90 dollars you multiply $15 • 6. So you would multiply $6 • $6
Answer: $36
        
                    
             
        
        
        
1st angle  - x⁰
2nd angle - (x+25)⁰
The angles are supplementary,
so
x+x+25=180
2x=155
x=77.5⁰ -1st angle
77.5+25=102.5⁰ - 2nd angle
        
             
        
        
        
Answer:
1/4 to the 3rd power is 0.015625
Step-by-step explanation:
Im assuming that is what your asking, you worded it a little differently. When you figure out what the value of something is based on the power it is raised to, you multiply that number by itself the amount of the exponent.
1/4 x 1/4 x 1/4 =  0.015625
 
        
             
        
        
        
5(a + 3b) = 5(9 + 3(2)) = 5(9 + 6) = 5(15) = 75
