Answer:
so, the width of the poster is 8.185 inches [rounded] / √67 inches
and the length of the poster is 13.185 inches [rounded] / √67 + 5 inches
Step-by-step explanation:
( area can be found with the formula l × w [length × width] )
I will call the width "x"
w · l = 72
x · x + 5 = 72
- 5 - 5
x · x = 67
x² = 67
√x² = √67
x ≈ 8.185
(x = √67)
so, by adding 5 inches, we get that
x + 5
8.185 + 5 [√67 + 5]
length = 13.185
so, the width of the poster is 8.185 inches [rounded] / √67 inches
and the length of the poster is 13.185 inches [rounded] / √67 + 5 inches

Answer:
Step-by-step explanation:
Tracey Earns in week= $102.45
Tracy=2x-12.45
102.45=2x-12.45
2x= 102.45+12.45
2x=114.90
x= 114.90/2
x=$57.45
Kayla earns 57.45 dollars
X-13<64
X<77
That's your answer.
