(2 + 7) - (3 + 4 + 4)
2 + 7 = 9:
9 - (3 + 4 + 4)
3 + 4 = 7:
9 - (7 + 4)
7 + 4 = 11:
9 - 11
9 - 11 = -2:

Answer:
B) -5
Step-by-step explanation:
let the number be x
2x=x-5
take x to the other side
2x-x=-5
×=-5
L=W+12
2L+2W=48
2(W+12)+2W=48
2W+24+2W=48
4W=48-24
4W=24
W=24/4
W=6 ANS. FOR THE WIDTH.
L=6+12=18 ANS. FOR THE LENGTH.
PROOF:
2*18+2*6=48
36+12=48
48=48
Hope this helps:)
