Answer:
7.1
Step-by-step explanation:
write pythagorean theorem 
+ = 
2
= 100
divide 2 both side:
= 50
= 
=
= 7.07106781
round to nearest tenth:
= 7.1
D. X = 8 , Y = 6
3x - 14 = x + 23x - x = 2 + 142x = 162x / 2 = 16/2x = 8
To check: 3x - 14 = x + 2 ; 3(8) - 14 = 8 + 2 ; 24 - 14 = 10 ; 10 = 10
4y - 7 = y + 114y - y = 11 + 73y = 183y / 3 = 18 / 3y = 6
To check: 4y - 7 = y + 11 ; 4(6) - 7 = 6 + 11 ; 24 - 7 = 17 ; 17 = 17

Answer:
48cm^2
Step-by-step explanation:
First, you can break down this shape into two different, easier to work with shapes, with dimensions of 4*9 and 6*2. You can get this by cutting the bigger rectangle into the 4*9, and then using the 6*2 left over.
After that, all you need to do it multiply and then add.
4*9 is 36, and 6*2 is 12.
36+12=48
Hope this helped!
