For any triangle, the 2 shortest sides added together have to be longer than the longest sides.
short side (10) + short side (5) needs to be greater than (>) longest side (20)
10 + 5 > 20
15 > 20
This inequality is incorrect, so the lengths cannot make a triangle.
Hope this helps :)
Answer:
k = -2
Step-by-step explanation:
1. Substitute the point (2,-1) into the given equation 5x+ky=12. The first number is 2, the x-value. The second number is -1, the y-value.
5x + ky = 12
5(2) + k(-1) = 12
2. Simplify
5(2) + k(-1) = 12
10 + (-k) = 12
10 - k = 12
2. Isolate k
10 - k = 12
-k = 12-10
-k = 2 <= here multiply both sides by (-1)
k = -2
I would need see what your choices are to give exact answers, but I think the main idea here is to see that angles 1 and 3 are the same, and since the alternate interior angle theorem states parallel lines through a line, or another set of parallel lines, form equal angles on those positions, the lines that form those angles, p and q, must be parallel.
Answer: a²+2b+2ab
Step-by-step explanation:
(2a²+62+2b+1)-(a²+62-2ab+1)
2a²+62+2b+1 - a²-62+2ab-1
a²+2b+2ab
A. The data shows roughly a doubling every month, exponential growth
B. Like I said, there's roughly a doubling every month, about 100% growth per month
C. Month 7 would be about half of month 8, maybe a little less than half, 5.74 /2 = 2.3
Answer: 2.3
