4b - 6b + 19
Answer : -2b + 19
Use Pythagorean theorem
a^2 + b^2 = c^2
Plug in the info
b = 53, a = 41
41^2 + 53^2 = c^2
1681 + 2809 = c^2
c^2 = 4490
Squareroot of 4490 = 67.007
Perimeter = adding all sides
53m + 41m + 67.01m = 161.01 m
Solution: 161.01 meters
Answer:
44%
Step-by-step explanation:
For these types of problems, look at the totals. We know that there are 0.44 out of 1 eighth graders. Since it doesn't specify how the 8th grader is dropped off, we take 0.44 and divide it by 1 (the total). We get 0.44, but since it's most likely asking for percentages, multiply that by 100.
Answer:
I. B. true
II. A true
Step-by-step explanation:
we can use the quadratic equation:
we have:
1)
a=1 b=-4 c=5
the quadratic expression has two complex factors.
2)
a=1 b=-5 c=14
the solution of are
3)
a=2 b=-8 c=5
11x+3=0
11x+3_3=0_3
11x=_3
11x/11=_3/11
x=_3/11
