Answer:
yard
Step-by-step explanation:
Length of string Mrs. Ruiz has = 
yard
Mrs. Ruiz needs to hang 3 banners using the string.
Having known that each banner uses same length of string to be hung we can divide total length of sting into 3 equal parts.
So, we can divide yard by 3 as
⇒

∴ Mrs. Ruiz must used yard of string for each banner.
Answer:
Step-by-step explanation:
7-(6/2)^2+2 = 4
pemdas
Parenthasis : 7 - (3) ^2 +2
Exponents : 7- 9 + 2
Multiplication : x
Division : x
Addition : 7-11
Subtraction : 4
A^2+14a-51=0
Add 51 to both sides
a^2+14a-51+51=0+51
a^2+14a=51
add (14/2)^2
a^2+14a+(14/2)^2=100
Solve a+7=+sqrt 100: a=3
Solve a-7 = -sqrt 100: a=-17
a=3 a=-17
