Answer:
32
Step-by-step explanation:
25% is the same as 1/4
8 times 4 is 32 so 8 is 25% of 32
Coplanar lines are line witch lie on the same lie on the same plane. two parallel lines or two intersecting lines always lie in a plane. Thus, two line are coplanar, if and only if they are either parallel or intersecting. lines in three dimensional space are coplanar, only if they are not skewed lines.
For example: Square has dimension a
A = a² and if every dimension is multiplied by k new dimension would be:
A 1 = k² a² = k² A.
Or the area of rhombus: A = d1 * d 2 / 2
New area is: A 1 = k d 1 * k d 2 / 2 = k² A
Answer: If every dimension of two-dimensional figure is multiplied by k, the area is multiplied by k².
Factor this by grouping. Group the first two terms together and then the second 2 terms together. The idea here is that, after grouping, what you can pull out in both groups is the same. Like this:
Now work on finding a common thing between the 2 groups:
See, what you have in common there now is the (x-9) that you can factor out:
And that is factored completely.
Answer:
F(n) = 8.5*n yards, where n is the number of windows
Step-by-step explanation:
Suppose the house of Stephen's aunt has n windows.
Since he needs 8.5 yards of fabric for each window, then he needs 8.5 times n yards of fabric for the n windows.
Call F(n) the yards of fabric he needs for the n windows, then
F(n) = 8.5*n
For example, if auntie's house had 4 windows, then
F(4) = 8.5*4 = 34 yards.
If auntie's house had 6 windows
F(6) = 51 yards.
