Answer: perm will cost $48
Step-by-step explanation:
Let x be cost of haircut
So perm will cost her 2x
So
x + 2x + 5 = 77
3x = 72
x = 24
Perm will cost 2x24 = 48
Lets say w is the width of the flower bed. We can make an equation to find the area.
The length of the of the flower bed is (w+5) and the width is w.
To find the area we need to multiply the length(w+5) by the width(w) and set it equal to 84,
(w+5)(w)=84
w^2 +5w=84
Using the quadratic equation you get the solutions of 7 and -12. Since 7 is positive it is our width. Our length is 7+5 or 12.

Step-by-step explanation:
x²-7x+10=0
(x-2)(x-5)=0
x=2 or x=5
Answer:
5
Step-by-step explanation:
sqrt[(-8+3)² + (-6+6)²] = 5
The answer is 2,925
to get the answer: 26*112=2912 .5 equals half an hour so half the pages
so you add 2912 + 13= 2925
