Answer:

(y+3) (x^2+3)

Step-by-step explanation:

x^2y + 3x^2 + 3y + 9

I will factor by grouping

Taking the first two terms I can factor out x^2

Taking the last two terms I can factor out 3

x^2y + 3x^2     + 3y + 9

x^2(y+3)           + 3(y+3)

Now I can factor out (y+3)

(y+3) (x^2+3)

Since(x^2+3) and (y+3) cannot be factored , this is completely factored

Answer:

(y+3) (x^2+3)

x^2y + 3x^2 + 3y + 9

x^2(y+3)           + 3(y+3)

(y+3) (x^2+3)

A deli sells a sandwich spread for 6.4per pound. How much do you need to pay for 24 ounces of spread?
Dafna1 [17]

Answer:

You have to pay 9.6.

Step-by-step explanation:

In order to find the answer, first you have to consider that 1 pound is equal to 16 ounces and with that information, you can use a rule of three to find the pounds that 24 ounces represent:

1 pound → 16 ounces

    x       ← 24 ounces

=(24*1)/16=1.5

Now that you know, that 24 ounces are equal to 1.5 pounds you can multiply the price per pound for the number of pounds to find the amount that you need to pay:

6.4*1.5=9.6

According to this, the answer is that you have to pay 9.6.

The number of loaves of bread purchased and the total cost of the bread in dollars can be modeled by the equation c = 3.5b. Whic
Valentin [98]

Answer:

Loaves of bread: b can't be a negative value, then the first table doesn't include viable solutions.

The number of loaves of bread must be a whole number, then the second table doesn't include viable solutions.

c=3.5b

if b=0→c=3.5(0)→c=0

If b=3→c=3.5(3)→c=10.5

If b=6→c=3.5(6)→c=21

If b=9→c=3.5(9)→c=31.5

The third table includes viable solutions
