Answer:
-3x^2-15x-30
Step-by-step explanation:
Let's simplify step-by-step.
−3(x+3)2−3+3x
Distribute:
=−3x2+−18x+−27+−3+3x
Combine Like Terms:
=−3x2+−18x+−27+−3+3x
=(−3x2)+(−18x+3x)+(−27+−3)
=−3x2+−15x+−30
Answer:
The Answer is C.
Step-by-step explanation:
It is moved 2 spaces and is flipped from q1 to q4.
Answer:
<h2> 18.3</h2>
Step-by-step explanation:
from cosines theorem:
t² = 11² + 14² - 2•11•14•cos87°
t² = 121 + 196 + 308•0.05236
t² = 333.12688
t = √333.12688
t = 18.2517... ≈ 18.3
There are 52 weeks in a year.
Using 50 for the number of weeks in a year is a(n) round.
Rounding is a process which we approximate the known number by just scaling it up or down.
In rounding the numbers less than 5 are scaled to one number less than the given integer and numbers such as 5 or above than 5 are scaled a number greater than the given number .
For example if there were 55 or more than weeks in a year we can say there are approximately 60 weeks in a year.
But there are 52 weeks so we <u><em>round</em></u> it to 50 weeks as 2 is less than 5.
