4n + 8 = n - 7
(In which 'n' represents the unknown number)
(4n + 8): "Eight more than the product of four and a number"
(= n - 7): "Is equivalent to seven less than the same number in equation form."
Subtract 8 from both sides:
4n = n - 15
Subtract n from both sides:
3n = -15
Divide both sides by 3:
n = -5
Answer:
D
Step-by-step explanation:
20x + 12 x =14x +30
20x - 14x = 30-12
6x= 18
6x/6 = 18/6
x = 3
so xs =3
So you want to find the area of each side
8X10=80
8x6=48
8x8=64
10X6=60
80+48+64+60=252
So the surface area is 252 yds
8/3
divide both sides by 3 and you get x=8/3
Answer:
3/1
