Step-by-step explanation:
he has 1/4 remaining as he has only used 3/4
2x+7=?
X=6
2(6)+7=
12+7=19
In six years, the tree will be 19ft
2x+7=44
Minus seven on both sides
2x=37
Divide two from both sides
X=18.5
Thus, it will take 18 and a half years for the tree to reach 44ft
14+14=28
48-28=20
20 divided by 2 =10
The width is 10
