Just matter of combining like terms
6x - 7 - 11x + x =
(6x + x - 11x) - 7 =
(7x - 11x) - 7 =
- 4x - 7 <===
Answer:
22155.84 in
Step-by-step explanation:
r = 84 in
π = 3.14
then area if circle = r² × π
… A = 84² × π = 22155.84 = ( 22.15584 min )
Ok brother tell me what is your problem
Answer:
cos y = r/q
Step-by-step explanation:
Sine is opposite divided by hypotenuse. Here, since sin y = 7/q, we can say that the opposite side length is 7 and the hypotenuse side length is q.
Tangent is opposite divided by adjacent. Here, since tan y = 7/r, we can say that the opposite side is 7 (just like above with sine) and the adjacent side is r.
Now, we have a triangle with its two legs labelled 7 and r and its hypotenuse labelled q.
Cosine is adjacent over hypotenuse. Because the adjacent side has a length of r and the hypotenuse has length q, we know that cos y must be r/q.
Hope this helps!
I mean I can give you a pretty vague answer. Geometry is essential for building anything. If you want to build a house, how big do you want it? What area should each room have. If you want to build a fence around your house how big should the perimeter be? With anything we build, geometry places an important role.
