Answer:
2x5y2−8x4y2−18x3y2+5x2y2−20xy2−45y2
Step-by-step explanation:
y2(2x3+5)(x2−4x−9)
=(y2(2x3+5))(x2+−4x+−9)
=(y2(2x3+5))(x2)+(y2(2x3+5))(−4x)+(y2(2x3+5))(−9)
=2x5y2+5x2y2−8x4y2−20xy2−18x3y2−45y2
=2x5y2−8x4y2−18x3y2+5x2y2−20xy2−45y2

Answer: Linear pair
Step-by-step explanation:
They are a linear pair because
1) their angles add up to be 180 so complementary is out
2) they aren't vertical of each other so vertical angles is out
And 3) they aren't adjacent angles
We know that the number of workers doubles every week.
This implies that the number of workers of the previous week is exactly half of the current one's.
So, it took 11 weeks for the factory to be at half capacity.
Answer:
A = 25 in^2
Step-by-step explanation:
The area of a triangle is given by
A = 1/2 bh
A = 1/2 (10)(5)
A =1/2 *50
A = 25 in^2
Answer:
C (33/100)
Step-by-step explanation:
4/10 can also be written as 40/100 (multiply both numerator and denominator by 10)
This means
40/100 + what equals 73/100.
40+33 is 73 so, the answer is 33/100
