Answer: 2.592 x 10^6 seconds
Explanation:
There are 3600s in 1 hr
And 24hrs in 1 day which mean
There are 3600 x 24 = 86400s in 1 day
And one month = 30 days
86400 x 30 = 2, 592, 000s in 1 month
Write in scientific notation:
2, 592, 000 = 2.592 x 10^6
Answer:
C: x^4+6x^3-12x-72
Step-by-step explanation:
For the function : f(x)=√x^2+12x+36
It can be factorized to
f(x)=√(x+6)²
=x+6
f(x)*g(x)
=(x+6)(x^3-12)
Expand the brackets
=x^4-12x+6x^3-72
rearrange the numbers
x^4+6x^3-12x-72
There are 9 unit squares, 4 2x2 squares, and 1 3x3 square, for a total of 14.
