Answer:
We know that ,
Number of zeroes in a polynomial = degree of the polynomial
( degree of polynomial = the highest power in the polynomial )
therefore ,
hope helpful~
Yes. If the diagonals bisect the angles, the quadrilateral is always a parallelogram, specifically, a rhombus.
Consider quadrilateral ABCD. If diagonal AC bisects angles A and C, then ΔACB is congruent to ΔACD (ASA). Hence AB=AD and BC=CD (CPCTC).
Likewise, if diagonal BD bisects angles B and D, triangles BDA and BDC are congruent, thus AB=BC and AD=CD. (CPCTC again). Now, we have AB=BC=CD=AD, so the figure is a rhombus, hence a parallelogram.
The answer is <span>4 3/4 yards of the fabric.</span>
This can be calculated using the proportion.
If the 3 1/6 yards of the fabric is enough for <span>1 1/3 shirts, how many yards are necessary of 2 shirts:
</span>
Let's express 3 1/6 as 19/6:
Similarly, 1 1/3 = 4/3:
Now, let's use this in the proportion:
<span>
</span>
Crossing the products:

Therefore, Mary needs in total 4 3/4 yards of the fabric.
It’s 8.9 because in a simpler way 8 is greater than 7
