180-65=115
Answer:
B. You have to distribute properties. So you distribute the exponent 5 to both the 6 & the 9
The answer is 486.6
There are 8,760 hours in a year, so 18 divided by 8,760 would = 486.6
I believe the answer is "C"
Answer:
11, 13 and 15.
Step-by-step explanation:
Let's say that the odd number is "x". If x is for example 15, then the next ODD number would be 15+2=17 and the one after that would be 15+2+2=15+4=19.
Applying that here, we get:
Odd number* the next odd number*the next odd number=2145
x*(x+2)*(x+4)=2145
x*(x^2+4x+2x+8)=2145
x^3+6x^2+8x=2145
By solving the polynomial, you get x=11.
Which makes our three numbers: 11, 13 and 15.
11*13*15=2145. The answer checks.
