10 minutes before 9 is 8:50. since any time on the hour is at a perfect 60 minutes, you subtract the minutes given and move 1 hour back to find your answer.
for example, if you were asked what 20 minutes before 10 was. you start by subtracting 20 from 60. 60-20= 40, this being your minutes. 10-1 is 9, this being your hour, making the final answer 9:40.
Answer:
10/2x^2+2x+2=2x-1+y
y=5x^2+1
Step-by-step explanation:
The pattern in this is
, where n is the previous number in the sequence and x is the number you multiplied a number by to get the previous number. You start with twelve times two, then increase the number you multiply by by one.
The next number in the sequence is
1440.
Answer:
168 square inches
Step-by-step explanation:
Assuming these are the dimensions of a rectangular prism, then the surface area is given by
TSA=2(lw+lh+wh)
We substitute the dimensions into the formula to obtain:
TSA=2(2*9+2*6+9*6)
We simplify to get:
TSA=2(18+12+54)
TSA=2(84)
TSA=168 square inches
