Multiply the numbers on the major axis which are 2 and -9 to get -18. Subtract from that 3*4 = 12. So -18-12 = -30. That's the determinant.
Factor w+1 out of 4x(w+1)+5y(w+1).
(w+1)(4x+5y)
plzmark me as brainliest :)
It would be 2/5 but the numbers between is 2/10 and 3/10
Step-by-step explanation:
1. draw the parallelogram with side 20cm and 25cm respectively and also the diagonal as well.
2.Clearly it forms a triangle in the parallelogram with three known lengths of side.
3.Using the cosine rule : c^2=b^2+c^2 -2bc cos c to find the obtuse angle.
Yes, yes it is!
Because every point on the line of this equation is also a solution!
THis is called a linear equation!
