The given expression is a result of squaring binomials
<h3>Factoring quadratics </h3>
From the question, we are to determine whether the given expression is a result of multiplying conjugates together, squaring binomials, or neither
The given expression is
9z² +54z +81
To do this,
First, we will factor the expression
Factoring the expression
9z² + 54z + 81
First, factor out 9
9(z² +6z +9)
9(z² + 3z + 3z + 9)
9[z(z + 3) + 3(z + 3)]
9[(z +3)(z +3)]
9[(z +3)²]
This can further be expressed as
3²[(z +3)²]
[3(z +3)]²
(3z +9)²
Hence, the expression is a result of squaring binomials

Answer:
(2,3)
Step-by-step explanation:
Hey there!
when it ask for the solution of a systems of equation it's essentially asking for where the two lines cross
the two lines cross at (2,3) therefore 2,3 is your answer
Y/x^2
You have to subtract or add exponents
The plumber's 2 hour and 26 min plumbing bill cost is $73
What is the plumber's per minute rate?
The plumber's per minute rate is the per half-hour rate divided by 30 minutes since the plumber charges $15 for every 30-minute job
per-minute rate=$15/30
per-minute rate=$0.50
Now, let us convert 2hours and 26 minutes to minutes, in other words, every 1 hour is 60 minutes, the two hours equal 120 minutes plus the 26 minutes gives a total of 146 minutes
Total minutes=120 min+26 min
total minutes=146 minutes
Total plumbing bill cost for 146 minutes is $0.50, the per-minute rate multiplied by the number of minutes the plumber needs to work in this case
2 hour and 26 min plumbing bill cost=146*$0.50
2 hour and 26 min plumbing bill cost=$73
