Answer:
10x^9
Step-by-step explanation:
Add the exponents together and multiply normally
2x^6+5x^3
=10x^9
You need to use the law of cosine:
B^2 = A^2 + C^2 - 2ACcos(b)
55^2 = 90^2 + 50^2 - 2(50)(90)cos(b)
0.841666 = cos(b)
b = 32.68
9514 1404 393
Answer:
5.5
Step-by-step explanation:
On the left, the lower segment (7) is half the length of the one above it (14). The same proportion will hold on the right.
x = 11/2 = 5.5
First you divide 12 by 3 to get 4, and then you multiply 210 by 4 to get 840, which is answer C. This is because if it is 210 patients per 3 weeks, 3 goes into 12 weeks 4 times, so you need to multiply. I hope this helps!
