Answer:
42 square centimeters
Step-by-step explanation:
The total of sides FA and AB will be half the perimeter of the rectangle, or 14 cm. Since AB is 9 cm, that means FA is 5 cm.
EF is the difference between EF and FA, so is 11 cm -5 cm = 6 cm.
FC is the same 9 cm length as AB, so we have enough information about the trapezoid to use the area formula:
A = (1/2)(b1 +b2)h
A = (1/2)(9 cm +5 cm)(6 cm) = 42 cm^2
The area of the trapezium is 42 cm^2.
Answer:
x = 2
y = - z (for example 2)
Step-by-step explanation:
2³+2³+(-2)³= 8+8-8=8
Answer: B represents 7
This problem is asking us to find halfway between 2 and 12.
[Method One]
12 - 2 = 10
-
10 / 2 = 5
-
2 + 5 = 7
<em>or</em>
12 - 5 = 7
[Method Two]

[Method Three]
We can count up from 2 and down from 12 until we hit the middle
2 12
3 11
4 10
5 9
6 8
7 7
