Answer:
8 blue seats in each section
Step-by-step explanation:
88 seats in 4 identical sections
88÷4 = 22 seats in each section
red+blue = 22
14+blue = 22
blue = 22-14
8 blue seats each section
Equation:
No. of blue seats = (88/4) - 14

Answer:
(c) No, it is not a rectangle because the diagonals are not congruent
Step-by-step explanation:
The diagonals of a rectangle bisect each other and are the same length. The lengths of the diagonals of this figure are ...
AC = √((8-0)² +(6-2)²) = √(64+16) = 4√5
BD = √((5-3)² +(2-6)²) = √(4 +16) = 2√5
The diagonals are different lengths, so the parallelogram is not a rectangle. This is described correctly in choice C:
No, it is not a rectangle because the diagonals are not congruent.
_____
The lengths are found using the distance formula:
d = √((x2 -x1)² +(y2 -y1)²)
Answer:
z=-7
Step-by-step explanation:
x+y=22(double the average as there are two parts
x+y+z=22 (as shown in the last part)+z=15 (average tripled as there are three parts
22+z=15
z=15-22
z=-7
