Answer:
11 1/4
Step-by-step explanation:
4,800 and 60, <span>
Compatible numbers are numbers that are close in value to the actual numbers and easy to add, subtract, multiply, or divide mentally</span>
I don't speak Spanish and I don't think you are going to find someone on here who does
8. ab = cd
.. 3x+4 = 4x-1
.. 5 = x
.. ab = 3*5 +4
.. ab = 19
11. Adjacent vertex angles are supplementary and opposite angles are equal. If the angles are vertex angles numbered in order around the figure,
.. ∠2 = 12°
.. ∠3 = 168°
13. If the quadrilateral is a parallelogram so that point E is the midpoint of both diagonals, it will be a rectangle when the diagonals are equal length.
.. ae = be
.. x +22 = 3x -18
.. 40 = 2x
.. x = 20 . . . . . will make segments AE and BE the same length
_____
In general, diagrams are helpful for geometry problems.
The x intercept means that F(x) = 0
sin(4x)/2x=0
Which means that sin 4x=0
4x E {(-1)^n arcsin 0 +npi | nE Z}
x E {npi/4}
For x between 0 and pi means that x E {0, pi/4, pi/2, 3pi/4, pi}.
I hope that this is the answer that you were looking for and it has helped you.
