We are asked to create a factorable polynomial that has a GCF of 3x. This can be done in many different ways, but we'll use the easiest one. This will be completing the square.
GCF: 3x
Suitable Polynomial: 3x³ + 18x² +27x
Other Expressible Ways:
1) 3x(x² + 6x + 9)
2) 3x(x + 3)²
We got this by creating a perfect trinomial, which is x² + 6x + 9, as it can be factored into the binomial (x + 3)². All we had to do is multiply 3x to x² + 6x + 9 and simplify. Hope this helped!

Nuts.com sells raw almonds for $10 per pound and roasted pistachios for $12 per pound. Christopher spends $70, before taxes and

sp2606 [1]

Christopher purchased 2.8 pounds of almonds and 3.5 pounds to roasted pistachios.

Step-by-step explanation:

Cost of almonds per pound = $10

Cost of roasted pistachios = $12

Total amount spent = $70

Weight of nuts = 6.3

Let,

Weight of almonds = x

Weight of roasted pistachios = y

According to given statement;

x+y=6.3 Eqn 1

10x+12y=70 Eqn 2

Multiplying Eqn 1 by 10

$10(x+y=6.3)\\10+10y=63\ \ \ Eqn\ 3$

Subtracting Eqn 3 from Eqn 2;

$(10x+12y)-(10x+10y)=70-63\\10x+12y-10x-10y=7\\2y=7$

Dividing both sides by 2

$\frac{2y}{2}=\frac{7}{2}\\y=3.5$

Putting y=3.5 in Eqn 1

$x+3.5=6.3\\x=6.3-3.5\\x=2.8$

Christopher purchased 2.8 pounds of almonds and 3.5 pounds to roasted pistachios.
