Step-by-step explanation:
Each segment joining midpoints is called a "midline." It is parallel to the segment not being joined, and is half its length. All the dimensions of the smaller triangle are half those of the larger triangle. (They are similar triangles.) The ratio of areas is the square of the ratio of side lengths:
2² : 1² = 4 : 1 . . . . . . ratio of triangle areas
Step-by-step explanation:
3x+x=-7-5
4x=-12
x=-12/4
x=-3
Answer:6n-5
This is an arithmetic sequence since there is a common difference between each term. In this case, adding
to the previous term in the sequence gives the next term. In other words,
Formula:A*n=a*1d(n-1)
Answer:
x=40
Step-by-step explanation:
8(1/2x + 5) = 200
4x + 40 = 200
4x = 160
x = 40
