11a) False. If you simplify 8/30 you get 4/15 not 2/15.
11b) False. If you simplify 6/15, you get 2/5 not 3/5.
11c) true. 5/15 can be simplified to 1/3.
Formula is 2(wl+hl+hw)
2[(7x20)+(15x20)+(15x7)]
=1090 cm^2
Step-by-step explanation:
4x+13y=-9y+3y=33
17x=-6y=33
It would be 6/21 but simplified it would be 2/7
Opposite value would be either changing from a positive to a negative or from a negative to a positive.
Absolute value is always a positive value
A) 7.2, -7.2, 7.2
B) -3.5, 3.5, 3.5
C) 5 1/2, -5 1/2, 5 1/2
