22 ( total) - 10 ( what she has already) = 12 ( the amount she needs to buy)
If 1 hair and = $1
Than 12 multiplied by $1 = $12

Thus, the set of ordered pairs is
See diagram
look a right triangle
for a right triangle
with legs legnth a and b and hypotonuse c
a²+b²=c²
so
the legs are 7 and the diagonal is c
a=b since all 4 sides of a square are equal legnth
7²+7²=c²
49+49=c²
98=c²
sqrt both sides
√98=c
(√49)(√2)=c
(7)(√2)=c
7√2=c
the legnth of the diagonal is 7√2 inches or aprox 9.899 inches
Answer:
990 square inches:)!

Step-by-step explanation:
-8x+5x-9=6
-8x+5x= -3x
-3x=6
6/-3
x=-2
Add 6 to both sides and divide both sides by 5
